A. The breakdown of rock into smaller pieces
B. The removal of weathered products from rock
C. A change in rock resulting from exposure to water
D. A chemical change in rock that weakens it
A is weathering B doesnt make much sense to me C if too much water is exposed into soil it would most likely become clay and D a rock is a mineral not a chemical substance, from this comment decide what sounds right
I could be wrong but B is what I think. Erosion acts upon process on the surface like water flow and wind, it removes soil, rock or dissolved materials.
