Scientists have always wondered why dinosaurs suddenly ruled the earth. It has been suggested that aliens interfere with the evolution of life on earth. Of course, this is absolutely nonsense! However, scientists suffered from insufficient evidence until geologists discovered that this sedimentary layer itself was not simple!
230 million years ago, a rainstorm lasted for 2 million years!
1In the early 1990s, British geologists Alastair Ruffell and Michael J Simms discovered that there was an unusual interlayer between the dry red sandstone at the beginning and end of Triassic, and the color of this sedimentary layer was different!
After their careful study, they found that these sediments contain traces of river silt, even peat and a large number of plant fossils that have not completely formed coal. Alastair Ruffell and Michael J Simms are almost certain that this material contains too much information!
Moreover, such sediments are found in almost every continent, whether in Africa or Europe, or in the Middle East or Asia, or even in plateau areas, which shows that there was a global flood at that time, but what kind of process it was, Alastair Ruffell and Michael J Simms were also puzzled!
Because the mainland was not separated at that time, there was only the super Pangea, and because the area was too large, it was difficult for water vapor to enter the hinterland. Therefore, except for areas near the ocean, the climate in the inland areas of Pangea is very dry. In this case, the vegetation is very sparse, and the only animal species are not many. Dinosaurs lived in the southernmost part of the mainland near the ocean, while the earth was occupied by birds and crocodiles, and of course, the ancestors of mammals-the two-toothed beast.
How did the flood happen?
Scientists are stuck here, so the arid mainland suddenly becomes a good place for geomantic omen. The curve turns too fast and the old drivers are left behind!
On September 16, 2020, a paper was published in the journal Science Progress, arguing that it was probably caused by the eruption of a super volcano, and the evidence came from the lava area across the west coast of modern Canada. According to geologists, this huge igneous region was formed 234 million years ago.
According to geologists' estimation, this volcanic eruption released at least 5000 billion tons of carbon dioxide into the atmosphere, which greatly changed the climate of the earth, thus leading to the transition of the earth from extreme drought to warm and humid times. Triassic vegetation changed from shrubs to tall trees, and a large number of creatures adapted to arid climate became extinct, so dinosaurs gained unprecedented development opportunities.
Won't carbon dioxide cause global warming? Why is there a rainstorm?
Carbon dioxide will cause serious greenhouse effect, which has formed a * * * knowledge. Volcanic events in Goulias Province released 5000 billion tons of carbon dioxide into the atmosphere, which led to ocean acidification and an increase in the average temperature of the earth.
Then the domino effect happened. First of all, many marine organisms that can't adapt to ocean acidification are largely extinct, and the increase of average temperature will lead to a significant increase in the evaporation of the ocean. According to the paper published in Science in 20 12, the sea temperature at that time rose from 2 1 to 36, while the sea temperature at the equator was as high as 40. This water temperature can burn everyone!
A large amount of water vapor enters the atmospheric circulation, which leads to a more serious greenhouse effect. These astronomical water vapor seeped into inland areas, which started the once-in-a-million-year rainy season, and the earth instantly changed from drought mode to tropical rain forest mode!
Another contributing factor is the uplift of the orogenic belt in the western United States, which is caused by the closure of the northern branch of Tethys (located in the eastern part of the present European continent). Appearing in the south of Lauesia, it makes the mainland form a pressure gradient line, thus promoting the formation of monsoon. The summer monsoon was intercepted by the West Milla Mountains and brought heavy rain. This hypothesis explains the origin of the sediments in Sittethys, indicating that the region turned to a humid climate at that time.
This rainstorm, which lasted for millions of years, pushed dinosaurs onto the stage of the overlord of the earth. They ruled the earth for more than 65.438+0.6 billion years until it was hit by an asteroid 65 million years ago!
In the rainstorm season of the earth, people are worried that it will appear again.
Since the industrial revolution, human beings have released about 280 billion tons of carbon dioxide into the atmosphere, resulting in a temperature rise of 1. 1.5, which is nothing compared with the carbon dioxide emission and temperature rise 232 million years ago. However, the problem is that with the intensification of global warming, the increase of ocean acidification and water vapor evaporation, and the release of methane from the Arctic tundra, the earth is heading for the last super rainstorm season.
We can believe that it is impossible to meet the conditions of the last rainstorm season without the super volcano eruption to help the earth, but at present, the critical point of the earth's ecology seems to have warned mankind in many aspects, such as the melting of the polar ice sheet, the fires in the Arctic, the fires in Australia and California, and the increasingly frequent fires in the Amazon rainforest!
The earth is moving towards an extreme world. The World Meteorological Organization has warned that the duration of typhoons and hurricanes has increased by 50% compared with 50 years ago due to rising global temperatures. What will happen in the future? If left unchecked, the future will be worse, but no one may know how bad it is.
