What is the peeling of rocks into layers of sheets called?
-
Landslide
-
Exfoliation
-
Earth flow
-
None of these
B
Correct answer
Explanation
Exfoliation is a weathering process where rocks peel off in concentric layers or sheets due to pressure release as overlying material erodes, or from thermal expansion and contraction. This is common in granitic rocks and creates dome-shaped formations like Half Dome in Yosemite. Landslide involves mass movement, and earth flow is a type of slope failure.
