Question

Quizplus · Accepted Answer

The most widely accepted theory for the cause of the Permian extinction event is widespread volcanic activity in Siberia, which released massive amounts of greenhouse gases and toxic substances into the atmosphere, causing global warming, acid rain, and ocean acidification, ultimately leading to the extinction of many species. There is some evidence to support other theories like an asteroid impact, but the Siberian Traps volcanic activity is the most likely cause of the extinction event.
