What can occur during the evolution of a hot spot?
A)An initial period of subsidence as magmas rise from the mantle
B)Formation of a fold and thrust belt
C)Formation of rifts that radiate out from the hot spot
D)Thickening of the crust beneath a passive margin
E)None of these are correct.

Question

Quizplus · Accepted Answer

Hot spots can cause the overlying crust to weaken and form rifts that radiate out from the hot spot, creating a chain of volcanic islands or seamounts. This process is seen in the formation of the Hawaiian Islands. Option A is incorrect because as magmas rise from the mantle, they often cause uplift rather than subsidence. Option B is incorrect because fold and thrust belts are associated with tectonic collisions rather than hot spots. Option D is incorrect because hot spots typically cause thinning of the overlying crust rather than thickening.
