What caused the five mass extinctions? All of the "Big Five" were caused by some combination of rapid and dramatic changes in climate, combined with significant changes in the composition of environments on land or the ocean (such as ocean acidification or acid rain from intense volcanic activity).
31 Αυγ 2024 · Mass extinction causes include climate change, geologic catastrophes (e.g. numerous volcanic eruptions), and meteor strikes onto Earth’s surface. Evidence suggests that microbes may have sped up or contributed to some of the mass extinctions known throughout the Geologic Time Scale.
