PLZ HELP Which statement describes an effect of large asteroid and comet impacts?A. They may cause continents to move. B. They may cause small craters on Earth’s surface. C. They may cause changes limited to within the crater. D. They may kick up dust and pollute Earth’s atmosphere.

Correct

B.They may cause small craters on Earth’s surface.

Explanation:

Asteroids and comets are solid particle of mass (Asteroids are rocky; comets are dirty snowballs.) that floats and revolves around the outer space. When this mass is pulled towards the earth, it tends to fall right into the earth surface. And, also, the asteroids tends to fall into the earth once few times in a centuries.

The effect of the asteroids hitting the earth would lead to the creation of craters on the Earth's surface (A huge whole like a dent on the earth surface). An Example is the one hat happened in 1908 -- An asteroid estimated at 50 meters across explodes above Tunguska, Siberia, blowing down trees across 2,000 square kilometre and killing a thousand reindeer, but apparently no people.
