Volcanoes & Mass Extinctions

火山与大规模灭绝

Description

Explain how large igneous provinces (LIPs) — massive outpourings of lava over millions of years — caused global warming and ocean acidification that drove mass extinctions; connect the Siberian Traps to the end-Permian extinction and the Deccan Traps to the end-Cretaceous event; explore how hydrothermal vents on the early Earth may have been the cradle of life; understand volcanoes as both destroyers and creators in the history of life

Assessment Prompt

Can your child explain how enormous volcanic eruptions millions of years ago may have triggered some of Earth's biggest mass extinctions — what's the chain of events from lava to species dying out?
