Question

Which of the following causes rocks to break down into smaller pieces?

A. Weather
B. water
C. time
D. all of the above

Answer 1

I would say D in a perfect situation, but time in of itself doesn’t really have so much of a say without all of the other variables. But the best one is D.

Answer 2

all of the above
rocks break down as time goes by, especially since it’s growing older
water + weather also breaks down rocks into smaller pieces
