What causes mass extinctions?

Answer 1

While multiple causes may result in mass extinctions, a major change in the earth's ecology, atmosphere, surface and water at rapid rates is a common cause in all the hypotheses.

Though there have been theories regarding the causes of the mass extinction, scientists have identified a number of the most likely ones, including: - asteroid collisions - flood basalt events (volcanic eruptions) - sea level falls

Methane eruptions, global warming, global cooling, and anoxic events—when the earth's oceans lose their extinction—are a few more events that could lead to mass extinction.

Almost all living things that have ever existed on Earth have gone extinct.
