Glaciers can deform internally to behave like a plastic material and flow because __________.
A) there are layers of pure liquid water between the annual layers of ice
B) there are round rock particles within the ice that act like little ball bearings
C) the bonds between successive layers of ice are weaker than those within a single layer, allowing the glacier to slip like a stack of cards
D) there are layers of air between the layers of ice

Question

Quizplus · Accepted Answer

Glaciers can deform internally and flow in a plastic-like manner because the bonds between successive layers of ice are weaker than those within a single layer. This structural characteristic allows the layers to slip over each other, similar to how a stack of cards can slide, facilitating the glacier's flow.
