What are the reasons for the five mass extinction on Earth?
The reasons for the five mass extinction on Earth were as follows: 1. ** Ordovian mass extinction (about 440 million years ago, ranked second among the five mass extinction events)**: The main reason is that the global climate has cooled, the Earth has entered the Ice Age, and the sea level has dropped significantly. At that time, there was a more mainstream hypothesis that a star 60 million light-years away from Earth exploded into a supernova. The gamma-ray burst produced by the two poles hit the Earth, and the energy produced for 10 seconds contained the energy of 10 suns, causing the Earth's atmospheric molecules to denature. 30% of the oxygen layer was taken away, and a large amount of sunlight directly reached the Earth's surface, causing the death of shallow sea algae, which led to the death or even extinction of marine life. 2. ** Devonian mass extinction (from the late Devonian to the early Charcoal period, about 377 million years ago, the longest of the five mass extinction)**: It may be the result of multiple asteroid impacts and volcanic eruptions. During the late Devonian period, plants moved to land without natural enemies and grew in large numbers, destroying the carbon-oxygen cycle. The increase in oxygen content and the decrease in carbon dioxide content led to a drop in the Earth's temperature. Many creatures could not adapt to the cold and went extinct. In addition, many asteroid impacts caused a small number of creatures to go extinct each time, but they accumulated to cause mass extinction. 3. ** The mass extinction at the end of the Permian period (251 million years ago, the most serious of the five mass extinction)**: Probably caused by the eruption of the mantle plume. In the late Permian, all the land was compressed into the Pangu supercontinent, and then separated due to volcanic activity and earthquakes. The eruption of the super mantle plume triggered volcanic eruptions, and volcanic debris ignited the forest, raising the temperature of the earth. The subsequent climate change led to the extinction of life. 4. ** Early Triassic-Period mass extinction **: The reference materials did not explicitly mention the specific cause of this mass extinction. 5. ** End of the cretaceous period mass extinction (65 million years ago)**: The view that led to the mass extinction of life is usually believed to be the impact of large asteroids or comets on Earth, the eruption of super volcanoes on Earth, the Earth experiencing a large ice age, and other factors that may change the climate of the entire Earth.
