Once their strength is exceeded, rocks near the surface behave like

A. modeling clay.

B. most metals.

C. glass objects.

D. caramel candy.

Well from what I know rocks near the surface, where temperatures and confining pressures are low, behave like brittle solids and fracture once their strength is exceeded. Its called brittle failure or brittle deformation. Beneath the surface they act like modeling clay or caramel.
