The rain was called "the wet period of the earth" by scientists, and the occurrence of this event was also published in the journal of scientific progress. We also called it "the Kani flood event".
During the flood disaster of Carney period, there was heavy rain.
According to the introduction of Chinese and British scientists, scientists have proved through geological and biological evidence that the "Canyon Flood" did happen 233 million years ago, and this event happened in the great changes of our earth's ecological environment. Through analysis, it is found that this catastrophic event may be caused by a large-scale volcanic eruption in Ranglia, western Canada, because after the large-scale volcanic eruption, a large number of greenhouse gases such as carbon dioxide were produced, which led to great changes in the climate.
This phenomenon, as we say now, caused by the greenhouse gas produced by volcanic eruption, caused the global temperature to rise rapidly, which changed the climate and promoted the increase of rainfall. Geologists Mike Simms and alastair Rouvre said that through this analysis, we came to the conclusion that during this period of the earth, the rainfall lasted about 6.5438+0 million years, which is what we call the earth's wet period, instead of 2 million years as everyone said. This is a wrong message, so please don't get me wrong.
After the Kani Flood, dinosaurs were pushed to the throne of hegemony.
The emergence of this event led to the extinction of some creatures, but at this time dinosaurs became the dominant species on the earth, so after the "Canyon Flood", dinosaurs were sent to the throne of the earth. Although a new round of species appeared on the earth, including the large-scale development of plants under the new round of climate change, modern coniferous forests began to expand. However, after the Kani flood, there were not many new creatures, only relatively many herbivorous reptiles.
In the new round of species renewal, I didn't expect a new round of changes on the earth, that is, the drought period, which is fatal to most creatures. At this time, dinosaurs took this opportunity to occupy the main food chain, and some turtles, crocodiles, lizards and mammals appeared, but in front of dinosaurs, these creatures were "side dishes". Of course, for dinosaurs, most of them are vegetarian dinosaurs, and only a few dinosaurs have evolved carnivorous dinosaurs.
So this is also the main reason why dinosaurs survived. Of course, the ecosystem gradually improved, which was more conducive to the survival of dinosaurs, so the spread of dinosaurs became stronger and stronger. That's why we now find that dinosaurs actually ruled a biological period, because no new creatures can stop them. That's the reason. Therefore, it is a "coincidence" that dinosaurs can become the "overlord" of the earth, just at the best time for biological renewal.
1 10,000 annual rainfall will be online again?
From the point of view of scientific research, it is true that from the point of view of volcanic eruption and greenhouse gas emission, this may happen to the earth in the future, because volcanic eruption reached its peak during the Carney period, emitting a lot of greenhouse gases such as carbon dioxide, which led to a new round of extinction on the earth. Therefore, if the global greenhouse gas peaks again in the future, it means that human beings may face such a climate state in the future, and the rainfall of 654.38+million years may be online again.
At least in this theory, it makes sense. Of course, if the next rain lasts for 6.5438+0 million years, it means that this event is likely to happen again, which is not good news for modern civilized life on earth. Because this means the beginning of the next round of mass extinction, but maybe we can't wait for this process. Although the ecosystem of the earth is getting worse and worse now, the earth may have entered the next round of mass extinction before this state.
According to scientists, that is, our planet may have entered the sixth mass extinction. It is also pointed out in the 2020 Earth Vitality Report that animals have decreased by two-thirds in the past 50 years. What does this mean? The earth's ecosystem is obviously unbalanced. If the ecosystem is not protected, it means that the next one will be in the highest area of the earth's ecosystem, not the highest occupied by human beings. This is a mutual situation, so the earth's climate is changing and human beings should wake up.
