 B)False

Question 10

Which of the following statements is NOT a reason why meteorite impact craters are much more common on the Moon than on the Earth?

Accepted Answer

A)  Many impact craters on the Earth are buried by sediment over geologic time and so we don't see them. 
B)  Many impact craters on the Earth are destroyed by plate tectonic processes. 
C)  Smaller meteoroids and comets tend to burn up and disintegrate in the Earth's atmosphere before striking its surface. 
D)  The Earth's crust is very strong and so it is difficult for meteorite impact craters to form there.
