Question

Quizplus · Accepted Answer

Plastic flow, also known as internal deformation, is the most important method of movement for glaciers. This is the result of the snow and ice in the glacier being under a great amount of pressure, causing it to flow like a viscous fluid. The other movements listed (glacial retreat, isostatic rebound, incremental advancement, and creep) may occur, but they are not the primary method of movement for glaciers.
