what happens in mechanical weathering of a rock? select one: a. the force of gravity makes the rock fall. b. the chemical makeup of the rock is changed. c. the rock becomes liquid and flows in a river. d. the size and shape of the rock are changed.
Answer
Brief Explanations:
Mechanical weathering is the physical breakdown of rocks. It changes the size and shape of rocks through processes like abrasion, freeze - thaw cycles etc. Chemical makeup change is chemical weathering, rock becoming liquid is melting (a different process), and gravity - induced fall is mass movement, not mechanical weathering.
Answer:
D. The size and shape of the rock are changed.
