D) oxidation.
E) thermal expansion.

Question

Quizplus · Accepted Answer

When rocks are exposed to sunlight, their temperature increases, leading to thermal expansion. This can cause the rocks to fracture or crack. Therefore, the best choice for this question is E. The other options, hydrolysis, frost wedging, carbonation, and oxidation, are all processes that work on rocks over a longer period of time, and are not directly related to temperature changes from sunlight exposure.
