Question

1/10
what were the two major events that led to the extinction of many species 66 million years ago?
volcanic eruptions and a massive earthquake
volcanic eruptions and an asteroid impact
an asteroid impact and a tsunami
a massive earthquake and a tsunami

Explanation:

Scientific consensus identifies two key events driving the Cretaceous-Paleogene extinction 66 million years ago: large-scale volcanic eruptions (Deccan Traps) that released climate-altering gases, and the impact of a massive asteroid at Chicxulub, Mexico, which caused immediate environmental destruction and long-term climate disruption. Tsunamis and earthquakes were secondary effects of the asteroid impact, not primary drivers of the extinction.

Answer:

Volcanic eruptions and an asteroid impact
