what type of weathering is illustrated by the cracks in the simulated granite outcrop below?

a frost wedging.
b abrasion.
c pressure release.
d salt weathering.

Explanation:

Pressure release weathering (also called exfoliation) occurs when overlying rock is removed, reducing pressure on buried rock. This causes the rock (like granite) to expand and crack parallel to the surface. Frost wedging involves water freezing in cracks, abrasion is mechanical wear, and salt weathering involves salt crystal growth. The granite outcrop’s cracks (parallel to surface) match pressure release.

Answer:

c. Pressure release
