Changkyun POV

"I don't know if I can Kyun. I have to study for the final tomorrow. It's my last one and I'm freaking out", she texts

I frown at the text

I haven't been able to see her as at all this week because of all her finals

I miss her

And I just got through a boring dinner with my grandmother, Daseul and her parents

I almost fell asleep at the table, I was so bored

Then I was forced to speak to Daseul as her parents and my grandmother left us alone to eat dessert

I didn't know what to say to her

She knows I'm only doing this because I have to

And I know that's why she's doing it

But she's acting like we're an actual couple getting married

She spoke to me all about the wedding and the new things she chose

Like the color of the napkins

Like I care

All I did was nod while I thought of Joanne

Wishing I was with her

Planning on seeing her

After Daseul left, I texted Joanne

And I'm not mad that she's saying no

I understand that school is important to her and she has to pass if she's going to Mongolia next semester

But I'm frustrated that I can't be with her

Unless....

"Bring your books. You can study at the motel. I'll help you"

I wait for her text back

"Really? Isn't that boring for you?"

"No jagi. It doesn't bother me"

"Well ok", she answers

"Great. I'll pick you up in half an hour"

That gives me enough time to drive home, change, pick a hotel and go get her

"Great. I'll get ready", she texts back

I send her a thumbs up emoji then go find my grandmother to say goodbye

---------------------------------------------------

"Uh the Cambrian period?", I ask her, looking at the flash card she made

"First geological period of the Paleozoic era and Phanerozoic Eon. Lasted 53.4 billion years"

Christ, she's a memorization machine

We already went through twenty cards and she got all the information on them right

I don't know what she's so worried about

"Proterozoic Eon"

"Geological eon spanning 2500 to 538.8 million years ago. Most recent part of the Precambrian "supereon." Longest eon of the Earth's geologic time scale. It's subdivided into three geologic eras the Paleoproterozoic, Mesoproterozoic, and Neoproterozoic"

"Uh yeah", I say, my eyes following the words she's saying

"Next", she orders

"What's the longest era of the Earth's geological history?"

Didn't she just answer this?

Wasn't it the proto something?

"Paleoproterozoic Era. 2,500 to 1,600 million years ago. First of the three sub-eras of the Proterozoic Eon. During this era that the continents first stabilized"

"Right", I say then go to the next card, "What are the subdivisions of the Paleoproterozoic Era in order?"

"Fuck. Uh Statherian Period, Orosirian Period, Rhyacian Period and....uh...and ..Ectasian Period"

I raise my eyebrows at the card breathing out

She's gonna freak out

"They're all right but the last one. Is it the Siderian Period? Am I saying that right?"

"Fuck", she yells, frustration on her face

"Baby it's ok"

"Give me the card and go to the next one", she growls

Uh ok

Wordlessly I hand her the card, which she slams down on the bed, and I just look at the next one

"The Archean Eon and its uh eras in order?"

"Second of four geologic eons of Earth's history, from 4,000 to 2,500 million years ago. Continents formed and the earliest known life started. Eoarchean, Neoarchean, Paleoarchean and Mesoarchean"

"You um got the order of the eras wrong"

"Goddamit!"

She takes the card from me and reads it to herself, "Eoarchean, Paleoarchean, Mesoarchean, Neoarchean. Eo, Paleo, Meso, Neo. Why can't I fucking remember it?"

I watch her whisper the order to herself over and over

She's really hard on herself

And really stressed

"Jagi, maybe you should take a break"

"No. Keep going"

"Jagi-"

"Just read it Kyun!", she snarls, making me jump

I've never seen her this worked up before

I take her hand, lacing our fingers and kissing the back of hers, "Ok baby"

I look at the next card, "Hadean and lunar divisions"

"Hadean", she says shakily, "Started with the formation of the Earth about 4.6 billion years ago and ended 4 billion years ago. The lunar divisions are.....uh...um...pre....pre.

Uh pre-n something....I..I can't remember"

Tears form in her eyes as she tries to wipe them, "I don't fucking remember. Goddamn it. Why can't I remember?"

"Jagi, when was the last time you slept?"

She looked so tired when I picked her up and now she looks even more exhausted

And it's only 8 pm

"Uh....not last night....I took an hour nap at seven..."

AM?

It has to be AM

It was seven when I got her

"The night before last night? I don't know. I finished my bio final then I went right to studying for geology."

"Baby you're exhausted. You can't remember the answers because you need to sleep"

"I can't sleep Kyun! I need to pass. If I don't I can't get into the study abroad program and I'm going to have to re-take the class and wait six months before I can apply again"

Her hands are shaking and she's on the verge of completely losing it

"When is the final tomorrow?"

"At four. I have to get the rest of the cards right, then go over my notes and the text book and fuck there's not enough time"

She bursts into tears in a panic and I grab her, hugging her to me

"Baby, it's ok. You're just overtired ok? You need sleep"

"I can't"

"Yes you can Jo", I tell her, running my fingers in her hair, "Jo, you're so smart ok. You know all this stuff. I'm one hundred percent sure you do. You're just messing up because you're exhausted and your brain can't think. If you keep going like this until tomorrow, you will fail."

"Kyun don't say that!", she sobs

"Then lay down with me and sleep ok? I'll set an alarm to wake us up at eleven. I'll bring you food and I'll help you study again ok? You already know all this stuff. It's just a review. And you'll be able to take your final after a night's rest and you'll ace it. I know you will. Just please try to sleep"

I know what it's like to be up for hours with no sleep

It feels like you're going crazy

You're mind is running a million miles a minute, all your thoughts are out of order and everywhere, you can't get a clear thought

That's what's happening to her and if she doesn't sleep it'll just get worse

"But..how long do you have the room for? We didn't plan on staying over"

"All night baby. Don't worry about that ok? Can you lay down with me?"

"I..I don't think I can sleep though"

"I'll help you relax ok?"

She nods, "Ok"

Kissing the top of her head, I let her go, moving all her stuff to the table

Getting out of my hoodie, I stay in my shirt and sweatpants, getting in the bed next to her

I kiss her softly, moving her to her back

Kissing her neck, I move on top of her, pulling her pants and panties down as I kiss down her body

"Kyunnie"

"Shh baby. I'm helping you relax so you can sleep ok?"

She bites her lip, nodding

Once I get her bottom clothes off, I open her legs and slowly lick up her pussy

She gasps, moaning softly

I run my tongue up and down, slowly, letting her feel all of my tongue

Her legs shake as I slowly eat her pussy

While she gets so much pleasure from this, I have to admit I do too

I love having my face, my mouth between her legs

I ate other girls out but I never enjoyed it as much as I do with her

Fuck, I'll gladly do it to her for hours, feeling her pussy against my tongue, tasting her, sucking her clit, tongue fucking her

I always liked getting blow jobs and even though she's amazing at it, I'd rather eat her out

If it's a choice between a blow job or going down on her, I'm eating her cunt

Moving my tongue over her clit, she gasps in pleasure as I keep the flat of my tongue against her bump, massaging it

Feeling it throb against my tongue

That feeling sends pleasure down my spine and I lick her faster

Her fingers move in my hair, holding on softly, her breathing becoming more labored

Gently taking her clit in my mouth, I suck softly, slowly, tugging on her, absolutely loving having it in my mouth

"Kyun", she whimpers, her legs trembling

Her other hand moves down, taking mine, lacing our fingers together and holding on

And it feels right

It feels like her hand belongs in mine, like it's supposed to be there

She moans my name, coming with the next suck of her clit

Her hand squeezes mine even harder

I play with her, sucking her through it until she finishes

Moving my tongue down, I taste her sweet cum, licking and cleaning everything up

And I can't help but moan as I do

"So good baby. Fuck you taste so good"

Moving one of her legs over my shoulder, I slip my tongue inside her, pushing in as far as I can with her clenching as hard as she can

I wiggly my tongue around, hearing her moan softly, then slowly pull out and lick up, between her pretty pussy lips

Sliding back down, I dip my tongue in again, slowly fucking it into her hole

"Kyunnie, please"

"Tell me what you want baby girl"

"Faster"

I oblige, tongue fucking her faster but still going as deep as I can

"Baby", she whines, her hips moving slowly, sliding her cunt up and down my tongue

Moaning softly, I continue to dip my tongue into her, feeling her clench around it, sending pleasure down my spine

"Kyunnie", she moans as another orgasm overtakes her, her hand in my hair keeping me against her pussy

Swallowing, I go back in for more until there's no more of her sweet cream left

Her legs start to close but I stop her

"One more. Please. Keep these gorgeous legs open for me jagi"

Her legs open for me again and I suck on her perfect clit, sliding my fingers inside automatically finding her spot, pressing on it and rubbing softly

She whimpers, her body shivering as I move my fingers in and out, my mouth tugging on her throbbing bump

Fuck I love it

Sucking a little faster, she moans, clenching on my fingers

Almost

Squeezing her thigh, I brush her spot and her orgasm starts, pussy fluttering around my fingers

I don't stop playing with her clit, helping her ride it out as she softly calls my name

"Kyun. Kyunnie"

After, I pull my fingers out, sucking her off them, then licking her pussy until her cum is gone

I sit up, moving next to her, taking her in my arms

She leans against me, her head on my chest, her forehead against my neck

"Ggg..give me a minute", she yawns

"No jagi", I tell her, lifting her hand and kissing the back of it, "Just stay"

"But you don't want-"

"No baby. I didn't do it to you to get something back", I tell her, running my fingers in her hair, "I wanted to help you relax and you are"

"But-"

"You need to sleep jagi. There's plenty of time for us to be together after your final"

"Are you sure?", she asks sleepily

"Absolutely", I assure her, "Sleep baby. I'm right here with you ok? I'll hold you all night"

She snuggles into me more, her hand gripping mine tight

It doesn't take long before her breathing evens out, her cute little soft snores the only sound in the room

She needed to sleep

It's evident by how fast she fell asleep

She's so hard on herself when it comes to school, working herself to death

I get it, she wants to do good, she wants to go to the dig site but she can't keep going like this at the expense of her health

She never would have made it through the night, staying awake

And she definitely wouldn't have done well on the final with next to no sleep

This way she can rest, I'll get her food in the morning and I'll help her study the rest of whatever she has to study

Which reminds me

I grab my cell from the dresser, opening the clock app and setting an alarm for 11 a.m.

Putting my phone down, I close my eyes, holding her tight

I'm not tired but I'm not getting up

I promised her I'd hold her all night and I will

---------------------------------------------------

"You got this jagi", I tell her as I pull up to her school

After a good night's sleep, food and her tea she was able to finish studying, blowing me out of the water at how much she knows about these time periods, I never heard of

And how easily she recited all the information

How detailed she is with what happened in each one

I teased her about being right about sleep and she stuck her tongue out at me

It was adorable

She really didn't need to study much, finishing early

So I gave her good luck sex, making her cum six times before her final

Needless to say she's relaxed and confident about the test

"Thanks Kyun. For helping me"

I smile at her, "Of course jagi"

She smiles back, so fucking gorgeously

Reaching out, I run my fingers in her hair, a cute blush appearing on her cheeks

"Remember baby, if you do good I'll eat your pretty pussy and fuck you until your cunt is numb"

She swallows hard but nods, "I'll do better than just good. Good isn't good enough"

I just smile wider, "I know you will baby. Text me when you're done and I'll come pick you up ok?"

She nods, "Yeah Kyunnie"

Moving my hand from her hair to the back of her neck, I pull her in for a kiss

Her arms move around my neck, kissing me back

I don't know why I want to kiss her so much

I shouldn't

I shouldn't be doing any of this

Going out with her, helping her study, dropping her off at school

Acting like a normal boyfriend when I'm anything but

And I'm not even her boyfriend

I'm just her sex buddy

I know that for me, it's more than that

I have feelings for her

Fucking Jooheon was right

I like her, she's funny, she's so smart and she's interesting

The fact that she's amazing in bed is such a huge bonus

I can't let these feelings get any stronger

I won't

I can't have her and that's the end of it

I have to eventually tell her I'm going to be married and stop this

Soon

But right now I'm just going to enjoy being with her

She pulls away, immediately pressing another kiss to my cheek

"See you later baby"

I nod, watching her get out of the car and go inside the building

Then I drive back to the hotel to wait for her

The Prehistoric Nature mod for Minecraft had an update that greatly improves the Precambrian! Now instead of a simple two-biome world where Ediacaran critters live under Cryogenian ice, there's loads of different biomes from different parts of the Precambrian to explore. Unlike the other dimensions the mod adds, the Precambrian dimension has very few actual mobile creatures going about, and all of those seem to be in the Ediacaran biomes, so it feels suitably lonely. I'll put a bunch of screenshots below the cut in whatever order I end up encountering stuff.

Neoproterozoic Microbial Plains are covered in microbial crusts, which break when you walk over them, making them quite crunchy. The little pools that dot the landscape have both red and green algae living in them.

Hadean Volcanic Wastes are suitably fucked up.

The Cryogenian naturally has both the land and sea entirely frozen over. However, underwater there's more going on than in the biomes depicting earlier eras!

Paleoproterozoic Regolith, a quite martian-looking biome showing a time before any trace of life on land.

The Ediacaran biomes are much more lively than the others, with the seas covered in Charnia and its friends, while there's even some cretures crawling around between them and jellyfish swimming. I quite like these underwater chasms running through the biome I found.

Archaean tide pools have signs of life here and there in the form of stromatolites and microbial mats. Due to the lack of oxygen, the sky ranges from red to yellow depending on the weather. There's full Archaean sea biomes to be found as well.

Mesoproterozoic Carpet has plenty of Tawuia, Grypania, and of course stromatolites.

@POETICandFUNNY: The story of the gömböc begins with a brilliant mathematician named Vladimir Arnold, who proved in 1995 that such a shape could exist. He did not make it or see it. He just knew it was possible, because he was good at math. He wrote down his proof and showed it to other smart people, who nodded and agreed. But nobody knew how to make this shape. Nobody knew what it looked like. Nobody knew if they would ever find it in the real world. That’s where two Hungarian engineers, Gábor Domokos and Péter Várkonyi, came in. They were fascinated by Arnold’s proof and decided to take on the challenge of finding the exact formula for the shape. They used computers and calculators and lots of paper to solve the puzzle. They named it the gömböc, after a word for a round dumpling, because they liked dumplings.

Ancient diamonds hold the secrets of how continents evolved Diamonds found in Brazil and Western Africa reveal the history of an ancient supercontinent. The secrets of how continents grew and moved throughout the early history of life on Earth have been revealed by the analysis of ancient, superdeep diamonds discovered in mines in Brazil and Western Africa. Tracing the complex history of the ancient supercontinent Gondwana These diamonds developed at the foundation of the supercontinent Gondwana between 650 and 450 million years ago. Supercontinents are large landmasses that are formed when many continents combine to form a single, massive location. Gondwana is one of the most notable ancient supercontinents. It existed from the Neoproterozoic to the Cenozoic era and included the landmasses that now make up South America, Africa, Antarctica, India, Australia, and the Arabian Peninsula. Now, isotope analyses of the tiny silicate and sulphide inclusions in the diamonds have revealed how this supercontinent formed, stabilized, and moved around the planet. “Superdeep diamonds are extremely rare and we now know that they can tell us a lot about the whole process of continent formation,” said Dr Karen Smit of the Wits School of Geosciences, who was part of the study. “We wanted to date these diamonds to try and understand how the earliest continents formed.” Diamonds are one of the very rare minerals resistant enough to survive and witness the supercontinent cycle. The supercontinent cycle involves the recurring construction and dissolution of supercontinents over hundreds of millions of years. It is driven by the movement of tectonic plates, which are large sections of the Earth's lithosphere that float on the semi-fluid asthenosphere beneath them. When paired with current plate tectonic models of continent migration, geochemical analysis and dating of the diamonds revealed that the materials formed at extremely deep levels beneath Gondwana between 650 and 450 million years ago, when the supercontinent covered the South Pole, explained Smit. A complicated history that reveals the origins of ancient supercontinents Diamonds have travelled incredibly far both vertically and horizontally within the Earth, as evidenced by their complicated history, which can be used to trace both the origins of the supercontinent and the last stages of its evolution. What the researchers found was that host rocks containing the diamonds were added to the supercontinent's base, and Gondwana effectively "grew" from below. Violent volcanic eruptions then transported the diamonds to Earth's surface 90 million years ago, and with them the secrets of how Gondwana may have formed. “We need this type of research to understand how continents evolve and move. Without continents there wouldn’t be life. This research gives us insight into how continents form, and it links to how life evolved and what makes our planet, Earth, different from other planets,” concluded Smit. Smit is currently working at the University of the Witwatersrand where she is a member of a team creating a new isotope lab and procedures to eventually conduct diamond inclusion analysis in South Africa.

Yale joins the ‘Snowball’ fight over global deep freeze periods

A Yale-led research team has picked a side in the “Snowball Earth” debate over the possible cause of planet-wide deep freeze events that occurred in the distant past.

According to a new study, these so-called “Snowball” Earth periods, in which the planet’s surface was covered in ice for thousands or even millions of years, could have been triggered abruptly by large asteroids that slammed into the Earth.

The findings, detailed in the journal Science Advances, may answer a question that has stumped scientists for decades about some of the most dramatic known climate shifts in Earth’s history. In addition to Yale, the study included researchers from the University of Chicago and the University of Vienna.

Climate modelers have known since the 1960s that if the Earth became sufficiently cold, the high reflectivity of its snow and ice could create a “runaway” feedback loop that would create more sea ice and colder temperatures until the planet was covered in ice. Such conditions occurred at least twice during Earth’s Neoproterozoic era, 720 to 635 million years ago.

Yet efforts to explain what initiated these periods of global glaciation, which have come to be known as “Snowball Earth” events, have been inconclusive. Most theories have centered on the notion that greenhouse gases in the atmosphere somehow declined to a point where “snowballing” began.

“We decided to explore an alternative possibility,” said lead author Minmin Fu, the Richard Foster Flint Postdoctoral Fellow in the Department of Earth and Planetary Sciences in Yale’s Faculty of Arts and Sciences. “What if an extraterrestrial impact caused this climate change transition very abruptly?”

For the study, the researchers used a sophisticated climate model that represents atmospheric and ocean circulation, as well as the formation of sea ice, under different conditions. It is the same type of climate model that is used to predict future climate scenarios.

In this instance, the researchers applied their model to the aftermath of a hypothetical asteroid strike in four distinct periods of the past: preindustrial (150 years ago), Last Glacial Maximum (21,000 years ago), Cretaceous (145 to 66 million years ago), and Neoproterozoic (1 billion to 542 million years ago).

For two of the warmer climate scenarios (Cretaceous and preindustrial), the researchers found that it was unlikely that an asteroid strike could trigger global glaciation. But for the Last Glacial Maximum and Neoproterozoic scenarios, when the Earth’s temperature may have been already cold enough to be considered an ice age — an asteroid strike could have tipped Earth into a “Snowball” state.

“What surprised me most in our results is that, given sufficiently cold initial climate conditions, a ‘Snowball’ state after an asteroid impact can develop over the global ocean in a matter of just one decade,” said co-author Alexey Fedorov, a professor of ocean and atmospheric sciences in Yale’s Faculty of Arts and Sciences. “By then the thickness of sea ice at the Equator would reach about 10 meters. This should be compared to a typical sea ice thickness of one to three meters in the modern Arctic.”

As for the chances of an asteroid-induced “Snowball Earth” period in the years to come, the researchers said it was unlikely — due in part to human-caused warming that has heated the planet — even though other impacts could be as devastating.

The research was supported by the Flint Postdoctoral Fellowship at Yale and the ARCHANGE project. Co-authors of the study are Dorian Abbot of the University of Chicago and Christian Koeberl of the University of Vienna.

How fluctuating oxygen levels may have accelerated animal evolution

https://sciencespies.com/nature/how-fluctuating-oxygen-levels-may-have-accelerated-animal-evolution/

How fluctuating oxygen levels may have accelerated animal evolution

Oxygen levels in the Earth’s atmosphere are likely to have “fluctuated wildly” one billion years ago, creating conditions that could have accelerated the development of early animals, say researchers.

Scientists believe atmospheric oxygen developed in three stages, starting with what is known as the Great Oxidation Event around two billion years ago, when oxygen first appeared in the atmosphere. The third stage, around 400 million years ago, saw atmospheric oxygen rise to levels that exist today. 

What is uncertain is what happened during the second stage, in a time known as the Neoproterozoic Era, which started about one billion years ago and lasted for around 500 million years, during which time early forms of animal life emerged.  

The question scientists have tried to answer is - was there anything extraordinary about the changes to oxygen levels in the Neoproterozoic Era that may have played a pivotal role in the early evolution of animals - did oxygen levels suddenly rise or was there a gradual increase? 

Fossilised traces of early animals - known as Ediacaran biota, multi-celled organisms that required oxygen - have been found in sedimentary rocks that are 541 to 635 million years old. 

To try to answer the question, a research team at the University of Leeds supported by the Universities of Lyon, Exeter and UCL, used measurements of the different forms of carbon, or carbon isotopes, found in limestone rocks taken from shallow seas. Based on the isotope ratios of the different types of carbon found, the researchers were able to calculate photosynthesis levels that existed millions of years ago and infer atmospheric oxygen levels. 

As a result of the calculations, they have been able to produce a record of oxygen levels in the atmosphere over the last 1.5 billion years, which tells us how much oxygen would have been diffusing into the ocean to support early marine life.

Dr Alex Krause, a biogeochemical modeller who completed his PhD in the School of Earth and Environment at Leeds and was the lead scientist on the project, said the findings give a new perspective on the way oxygen levels were changing on Earth. 

He added: “The early Earth, for the first two billion years of its existence, was anoxic, devoid of atmospheric oxygen. Then oxygen levels started to rise, which is known as the Great Oxidation Event.  

“Up until now, scientists had thought that after the Great Oxidation Event, oxygen levels were either low and then shot up just before we see the first animals evolve, or that oxygen levels were high for many millions of years before the animals came along.

“But our study shows oxygen levels were far more dynamic. There was an oscillation between high and low levels of oxygen for a long time before early forms of animal life emerged. We are seeing periods where the ocean environment, where early animals lived, would have had abundant oxygen — and then periods where it does not.”

Dr Benjamin Mills, who leads the Earth Evolution Modelling Group at Leeds and supervised the project, said: “This periodic change in environmental conditions would have produced evolutionary pressures where some life forms may have become extinct and new ones could emerge.” 

Dr Mills said the oxygenated periods expanded what are known as “habitable spaces” — parts of the ocean where oxygen levels would have been high enough to support early animal life forms. 

He said: “It has been proposed in ecological theory that when you have a habitable space that is expanding and contracting, this can support rapid changes to the diversity of biological life. 

“When oxygen levels decline, there is severe environmental pressure on some organisms which could drive extinctions. And when the oxygen-rich waters expand, the new space allows the survivors to rise to ecological dominance. 

“These expanded habitable spaces would have lasted for millions of years, giving plenty of time for ecosystems to develop.”

The findings - “Extreme variability in atmospheric oxygen levels in the late Precambrian”  - are published in the journal Science Advances.

Does Constructing multiple #skyscrapers pose a risk to the Earth's rotation and spinning? The world is rapidly growing more and more populous, and there are also more buildings on the planet. Does this alter the rotation of the Earth? What if the earth stands still? It might come as a surprise to you that some of the Mega-structures like Skyscrapers play a small but significant role in altering the rotation of the Earth. The earth's rotation may actually slow down if the construction is large and tall enough to increase the earth's moment of inertia. While constructing massive skyscrapers, we are raising some mass from the earth's surface to a height above it. This increases the earth's moment of inertia around its axis of rotation. China's Three Gorges Dam, delayed the rotation of the Earth by 0.06 microseconds The slowing of the earth’s rotation has been happening ever since the moon started orbiting the Earth. A day was just 18.7 hours long 1.4 billion years ago, in the Neoproterozoic era when the moon was 27,000 miles closer to Earth than it is now. According to the International Earth Rotation & Reference Systems Service (an organization in charge of global timekeeping), on June 29, 2022, the Earth's regular 24-hour rotation was 1.59 milliseconds quicker than usual, shattering the previous record for the shortest day in recorded history. The previous record was set on July 19, 2020, when the day had a deviation of 1.47 milliseconds from average. What if the earth stands still? The topology of the globe, including both the general shape of the world and the contour of the earth's oceans, is largely influenced by the speed at which the earth rotates. If the earth fully stopped rotating, you would have half a year of daylight and half a year of night-time. The surface temperature would vary according to latitude during the day for six months, being much hotter near the equator than at the poles, where the light rays are more slanted and heating effectiveness is lower. The atmospheric wind circulation pattern would change as a result of this long-term temperature differential, moving air from the equator to the poles as opposed to the current wind systems that are parallel to the equator. The oceans would inevitably move toward the poles if the globe remained still, creating land in the equatorial region. This would eventually lead to the formation of two sizable polar oceans and a massive equatorial mega continent. As long as we can envision, the earth's rotation will continue to slow down infinitesimally but steadily for years to come. The cumulative effect of these dynamic changes is that the globe is becoming resembles a sphere, but it will be billions of years before the globe stops spinning. How did the Three Gorges Dam Slow the Earth’s Rotation?

Fossils of Early Paleozoic creatures.

The Paleozoic Era began 543 million years ago, and ended 248 million years ago. Prior to this, during the Proterozoic Era, bacteria and archaea were in abundance, with the first animals appearing towards the end of the Neoproterozoic.

At the beginning of the Paleozoic was a great explosion of diversity among multicellular animals. Nearly all living animal phyla appeared within a few million years. Animals, plants and fungi colonized the land, and insects took to the air.

But at the end of the Paleozoic was the Permian extinction, the largest mass extinction recorded in the history of life on Earth. Marine life was the most affected, with 90% of marine animal species going extinct.

modern human society is SO not my vibe.

i belong with homo erectus circa 2million BC where my pathalogical aversion to bitter tastes and hypersensitivity to low noises would actually be useful 😭

#how's THAT for ~i was born in the wrong time~ snowflakeness #fuck off with that I Wish I Was Born In The 50s shit #that I Belong In The Victorian Era nonsense #catch me in the neoproterozoic era with my real family

Great Basin National Park: a Historical Rundown

The Great Basin lays just South of the 6 and 50 highway in the US, close to the border of Utah and covers much of Northern and Central Nevada, small parts of Wyoming, Idaho, Organ and California. The area is hardly populated with Baker, NV being the closest town.

In the 1800′s George Montague Wheeler led expeditions in the area as a topographer for the U.S. Army Corps of Engineers, along side him was GK Gilbert; who was the first to write a geological report of the area.

Later on in the 1800′s Absalom Lehman came to the basin in search for gold and other valuable minerals. However, he was unsuccessful and lived life as a rancher selling supplies and food to the miners that came through. By 1855 he made the marvelous discovery of caves above his ranch and began to give tours.

The caves and their tours became a staple of the area and was pronounced the Lehman Caves National Monument in 1922. About 64 years later the Great Basin was named a National Park in 1986.

Let it be told that the history of the Great Basin does exceed that of its story of becoming a national park, or any other instances of human history within it. It is within the rocks that the Great Basin tells its tales.

The Great Basin starts its story in a Neoproterozoic, Cambrian ocean that existed all the way until the Pennsylvania. Through out this time, the ocean levels rose and fell, which is told by the transgression and regression sequences in the ancient sedimentary rocks. It wasn’t until the upper Paleozoic that the tectonic activity shifted the continental shelf environment.

Unconformity lies within the early Mesozoic Era and has not yet been added to the narrative but the story continues on into the Late Mesozoic Era in which faulting and igneous intruding was present due to the Sevier and Laramide Orogenies. The activity of crustal thickening and shortening along with plutonic intrusion was carried out throughout the Early Tertiary Period in the Paleogene Epoch. Low grade metamorphism during the Mesozoic burial beneath thrust sheets occured in the Pole Creek Limestone, Prospect Mountain along with other older rocks from the Neoproterozoic and lower Paleozoic.

Throughout the Cenozoic Era there was much andesitic volcansim. The Snake Range accumulated ash flows, tuffs and conglomerates. Most of the Volcanoes are about as old as the Oligocene of the late Paleogene. From the Oligocene Epoch to the Miocene Epoch of the early Neogene, there is a major extension of Snake Range. The displacement of the Snake Range detachment fractured the upper plate rocks on the South side and exposed the lower plate to the Metamorphic Core Complex

From the Miocene, the entire region was uplifted and broken up by a series of normal faults the created the tilted Basin and Range, along with block faulting. Any further volcanism was of basaltic composition.

As far as the Quaternary climatic changes go, there was multiple instances of Alpine Glaciation, that occurred in the area. Their glacial decomposition left the Lehman Creek moraine at 8100ft and the Dead Lake moraine at 9500ft. The Pleistocene glaciation formed the Lehman Caves. They also eroded the summits of Snake Range. Constant down slope erosion continues to create immense weathering, along with snow that collects in the summit’s hollows. There is still a glacier left to be found in the cirque of Wheeler Peak, along with a rock glacier.
