Which of the following best describes physical weathering?
a. a series of chemical changes that wears away at rocks
b. the movement of rocks from one area to another
c. any large-scale event such as volcanic eruptions or earthquakes
d. a process that breaks down large rocks into smaller pieces

The answer would be:

D. A process that breaks down large rocks into smaller pieces.

Physical weathering if referred to the process of rocks breaking apart without changing their chemical composition. If you look at the other answers, none of them match the description of physical weathering.

Hope that helps! :)
