In a plastically flowing alpine glacier, the ____.
A) center of the ice flows slower than the sides
B) bottom of the glacier flows the fastest
C) center of the ice flows faster than the sides
D) the middle depths of the glacier flow the slowest

Question

Quizplus · Accepted Answer

Plastically flowing alpine glaciers have a faster flow rate in the center of the ice than the sides due to increased pressure and shear stress towards the bottom of the glacier. The bottom of the glacier will also typically flow faster than the top or surface layers. The middle depths of the glacier can vary in flow rate, but typically flow faster than the bottom due to reduced friction with the valley floor.
