Question

5 multiple choice 2 points which of the following was a major cause of the permian-triassic extinction, also known as \the great dying\? rapid evolution of land plants that altered oxygen levels the impact of a large asteroid in the yucatán peninsula global cooling and glaciation massive volcanic eruptions that released carbon dioxide and triggered climate change

Explanation:

The Permian - Triassic extinction was mainly caused by massive volcanic eruptions (Siberian Traps). These eruptions released large amounts of carbon dioxide, methane, and other gases. The release of carbon dioxide led to global warming (not global cooling), ocean acidification, and a decrease in oxygen levels (not due to rapid evolution of land plants). The asteroid impact in the Yucatán Peninsula is associated with the Cretaceous - Paleogene extinction (which wiped out non - avian dinosaurs).

Answer:

Massive volcanic eruptions that released carbon dioxide and triggered climate change.
