D) Rocks systematically get weaker from the surface to deep in the crust.

Question

Quizplus · Accepted Answer

The strength of continental crust typically increases with depth due to increased pressure, but beyond a certain depth, high temperatures lead to weakening of the rocks. This results in a strength profile where rocks become stronger with depth initially and then weaken deeper in the crust.
