Answer

Brief Explanations:

When large asteroids impact Earth, they can cause a layer of burned organic matter due to intense heat - fires. The impact can also lead to a change in average global temperature as dust and debris block sunlight. Mass extinctions have been associated with major asteroid impacts, like the one at the end - Cretaceous. 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 rather than asteroid impacts as a primary cause.

Answer:

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