You are presented with the quiz "What can happen when a rock interacts with wind over a long period of time?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "rocks interacting with wind over long periods of time causes weathering" and "when a rock undergoes erosion and weathering, it breaks down to form sediments". 

So, what's the best answer to the question?
