Video spoilers history, starting with the blitzkrieg on Poland

Looking at several other mass extinctions among the great extinction events, some of them can only be classified as moderate extinction events.

Not only the ancients, but even modern netizens were shocked.

"Huh? Two million years of rain is a small extinction?"

"If a small extinction is this serious, it will be difficult for the Earth to withstand a large extinction."

Earth: Mass Extinction? The Earth Doesn’t Care!

"The end-Ordovician mass extinction caused the extinction of 85% of species, but it can't be called a mass extinction?"

"I thought there were five mass extinctions, but it turns out there's only one, strictly speaking."

"In the first mass extinction, 75% of people died, in the second 70%, in the fourth 4%, and in the fifth 76%. "

"This third mass extinction at the end of the Permian period is unique, with a rate of up to 96%. "

Tianmu continued his story amidst everyone's surprise.

The screen first played some demonstration scenes of the end-Permian mass extinction.

There was a loud noise from the ground.

Rising up are burning mountains.

The volcano spewed out a large amount of magma and volcanic ash.

The magma, like a rushing river, flows freely on the ground.

The thick volcanic ash in the air is suffocating!

A moment later, a gust of wind blew past.

The volcanic ash turned into acid rain.

Fall to the ground.

The ground was corroding, the plants were withering, and the animals were wailing.

Eventually, acid rain, volcanic ash and mud flowed into the sea, and a visible death zone spread in the sea.

The shallow sea that was originally full of life,

It instantly became a restricted area for life.

All kinds of fish fell down one after another.

The sea water receded, and the fish and shrimp turned into white bones.

[The end-Permian extinction, also known as the Great Mortality Event. ]

[This mass extinction caused the most serious mass extinction event in the history of the Earth. ]

【More than 96% of the world's species are extinct! 】

[More than 70% of land vertebrates became extinct.]

[Insects are known for their strong vitality, but only 10 orders have become extinct throughout history.]

[Eight of these orders became extinct in this geological event.]

[Like the famous internet celebrity ancient creatures, trilobites, sea scorpions, etc., they have survived for a long time, but disappeared in this mass extinction. 】

[Compared to other extinction events, what is even more terrifying is that this extinction almost completely emptied the ocean. ]

[It also caused the extinction of 90% of marine life.]

[If we look at it from the number of individuals instead of species. ]

[The mass extinction caused the amount of life on Earth to drop by more than 99%. ]

[So how did this mass extinction event happen? ]

[Why is this one so terrifying compared to other mass extinction events? ]

【Let's adjust the world map to 2.5 million years ago. 】

【The world at that time was completely different from today. 】

[Under the influence of continental drift, almost all the continents are squeezed into a ball. ]

[Formed an extremely huge supercontinent Pangaea. ]

[Different continental plates are now squeezed together, and naturally they will continue to squeeze and collide. ]

[And plate movement is an important factor in volcanic activity. ]

[So that was also one of the most volcanically active periods in Earth's history.]

[We know that the temperature of the Earth's inner core can exceed 5000 degrees, and the pressure of the inner core reaches 360 million standard atmospheres.]

[It can be said that the interior of the earth is high temperature and high pressure, and it is very turbulent. ]

[This huge pressure will cause the high-temperature mantle magma to flow out along the weak points of the crust, forming a volcanic eruption.]

[But most of the time, the magma gradually cools down as it gushes out of the surface.]

[It will only have a partial impact on local areas, and will not destroy the global ecological environment. ]

【But in the ancient Pangaea period. 】

[The earth's crust is constantly being squeezed, and one day it will no longer be able to suppress the internal pressure. ]

[After a long period of small fights, one day, the earth's crust finally couldn't hold on any longer and reached its limit.]

【The general outbreak has begun.】

[This time, it is not a simple volcanic eruption. ] [It is a super mantle plume eruption! ]

[A super plume is a type of volcanic eruption, usually referring to a giant volcanic eruption with a diameter of more than 100 kilometers or an eruption depth of more than 700 kilometers underground.]

[Some super mantle plume eruptions even start directly from the core of the earth. ]

[This is the most terrifying primitive force from the interior of the earth. ]

[The earth's crust cracked, and countless underground magmas gushed out. ]

[The first place where it erupted was in the area of ​​Mount Emei in Sichuan today! ]

[A super volcano erupted, and countless magmas exploded. Instantly covering a large area around it! ]

【Wherever the magma reaches, all life is destroyed.】

【Ancient Sichuan fell into a hell of flames and black smoke. 】

[Continuous volcanic eruption, not counting the prelude and post-rock part. ]

[The main eruptive period alone lasted a million years.]

[After the massive amount of magma cooled, it became pitch-black basalt. ]

[The basalt created by the cooling of the magma not only has a distribution area of ​​more than 25 square kilometers, but is also up to 1500 meters thick.]

[And today, billions of years later, you can still see the black areas in the strata of Mount Emei.]

【Telling us about the horror of the mantle eruption. 】

[This round of mantle super-eruption is also known as the Emeishan Traps Event]

tomorrow.

As Xu Xiake listened to Tianmu's narration, he recalled what he had seen and heard in Mount Emei.

The basalt of Mount Emei really impressed travelers like Xu Xiake.

But at that time, Xu Xiake only regarded the thick basalt layer of Mount Emei as a strange natural landscape.

Didn't think much about it.

But looking back now, Xu Xiake felt shocked and terrified.

“I never thought that the basalt of Mount Emei would be the biggest killer that almost destroyed all the creatures in the world!”

"When I went to Mount Emei, I thought its topography was very strange and beautiful."

“I was also surprised at the thickness of the basalt layer.”

"But I never expected that Mount Emei was so violent in the past."

"He almost destroyed the world single-handedly."

"Now that I know what Tianmu said, maybe I should go to Mount Emei again."

"Study carefully the Emeishan Traps that caused the mass extinction."

Most ancient people, including Xu Xiake, saw the terrible Emeishan Traps event and the super mantle plume erupting from the earth's core.

Everyone thought this was the end-Permian extinction.

But unexpectedly, Tianmu spoke slowly at this time.

[The Mount Emei Traps incident took 100 million years to slowly torture lives around the world.]

【However, this is just a prelude. 】

[Or maybe it could be said that the Earth gave it a short period of adaptation before the explosion.]

[900 million years after the Mount Emei Traps event, the Earth’s ecological environment has not yet fully recovered from the Mount Emei Traps event.]

【The prelude ends.】

【The real doomsday catastrophe has begun. 】

[Another super mantle plume erupted in what is now Siberia! ]

[With the strength to tear apart the earth's crust, it made a shocking appearance in geological history! ]

[This time, the Siberian supervolcano eruption lasted for a relatively short period of time. ]

【Only 20 years.】

[But the erupted magma covers an area of ​​up to 700 million square kilometers! ]

[Even today, the area of ​​this dark rock exceeds 200 million square kilometers. ]

[The crazy supervolcano magma area is almost as large as the entire United States. ]

[The dark basalt that formed after cooling gave Siberia a thick crust.]

[Also known as the Siberian Shield event. ]

【Compare this to the Mount Emei dark rock incident. 】

[The magma ejected by the Siberian Traps event was more than 20 times that of the Emeishan event.]

[And it only takes 6 to 20 years. ]

[Its intensity can be imagined. ]

【And with the ultimate eruption of Siberia's volcano,】

[This time, the end-Permian mass extinction event really began to intensify. ] (End of this chapter)
