Question

Which of the following facts about Exfoliation is false?

(a) It is the phenomenon of peeling off of curved shells from rocks

(b) The change is accompanied by chemical weathering

(c) Internal structure of the rock is affected

(d) It occurs in thick or layered rocks.

The question was posed to me in final exam.

I'd like to ask this question from Geological Work of Atmosphere topic in chapter Geological Work of Natural Resources of Engineering Geology

Answer 1

The correct choice is (c) Internal structure of the rock is affected

Best explanation: The internal structure of the rock is not affected due to the process of exfoliation. The phenomenon of peeling off occurs only in the layered or thick rocks and is accompanied by chemical weathering, mostly near the margins and develop curved surfaces. So basically surface is affected and not the internal structure.
