Question

what evidence do scientists have that earth has been hit by large objects, like asteroids, in the past? check all that apply
layer of volcanic ash
layer of burned organic matter
change in average global temperature
mass extinctions
earthquake activity

Explanation:

When large asteroids impact Earth, they can cause wild - fires leading to a layer of burned organic matter. The dust and debris thrown into the atmosphere can change the average global temperature. Mass extinctions have been correlated with major asteroid impacts. A layer of volcanic ash is more related to volcanic activity rather than asteroid impacts directly, and earthquake activity is mainly due to tectonic plate movements, not typically a direct sign of past asteroid impacts.

Answer:

• layer of burned organic matter
• change in average global temperature
• mass extinctions
