Question 1

Exfoliation occurs because

Accepted Answer

A) water freezes in joints and expands. 
B) water combines with minerals and increases their size,thereby causing surrounding minerals to expand. 
C) overlying rock is removed,thereby allowing the underlying rock mass to expand and fracture. 
D) evaporated water leaves behind previously dissolved mineral to form crystals,which accumulate and grow over time,exerting pressure on the rock.
