HURRY PLEASE Which of the scenarios is NOT an example of mechanical weathering?
A. Roots can wedge their way between rocks, forcing small fissures to become larger cracks.
B. Tiny particles of sediment in the wind smooth a rock over time.

C. A wildfire burns down a forest of trees, leaving fertile ash behind.

D. Water can settle between rocks and then freeze, forcing cracks to become bigger.

C. A wildfire burns down a forest of trees, leaving fertile ash behind.

Explanation:

Mechanical weathering is, "The main process in mechanical weathering is abrasion, a physical process by which rocks and clasts are reduced in size. Abrasion by ice, water, and wind processes loaded with sediments can have immense cutting power", this is the exact definition and answer C does not have anything to do with rocks :), hope this helped!
