When pressure is removed from overlying rock, the pressure of deep burial is relieved, initiating pressure-release jointing. The joints then separate into curved slabs. This is known as
A) exfoliation.
B) frost wedging.
C) salt crystal growth.
D) spheroidal weathering.

Question

Quizplus · Accepted Answer

The process described in the question is known as exfoliation, which involves the separation of curved slabs of rock due to the relief of pressure that was previously applied. This process is different from frost wedging, salt crystal growth, and spheroidal weathering, which all involve other mechanisms of weathering and erosion.

When Pressure Is Removed from Overlying Rock, the Pressure of Deep
