Question 23 • Environmental Science A

Which statement best describes an effect of large asteroid and comet impacts?

Answer
A
They cause Earth's tectonic plates to stop moving.
B
They can create large craters on Earth's surface.
C
They only affect small, isolated areas.
D
They have no impact on organisms.

Explanation

Large asteroids and comets can strike Earth with enough force to excavate enormous depressions in the ground, called impact craters. They do not stop tectonic plate movement, and their effects can extend far beyond the immediate impact area, including affecting organisms.
