Question

which of the following is an example of chemical weathering?
o water breaking rocks
o plant roots splitting rocks
o acid dissolving limestone
o wind breaking down rock

Explanation:

Chemical weathering involves changes in the chemical composition of rocks. Acid dissolving limestone is a chemical - change process as the acid reacts with the calcium carbonate in limestone. Wind breaking down rock, plant roots splitting rocks, and waterbreaking rocks are physical weathering processes that change the rock's physical form without altering its chemical composition.
