A glacier undergoes ________ deformation in its upper part and ________ in its lower part.

Question

Quizplus · Accepted Answer

Glaciers undergo brittle deformation in their upper part because the temperature and stress levels are low, making the ice behave like a brittle solid. In the lower part, where temperatures and pressure are higher, glaciers undergo plastic deformation, where ice behaves like a plastic solid and flows more easily. Therefore, the correct choice is C, brittle in its upper part and plastic in its lower part.
