The relative rates of basal slip and plastic flow depend on the ____ of the bedrock underlying the glacier, the ____ of the ice, and the temperature of the glacier.
A) steepness; age
B) thickness; thickness
C) steepness; thickness
D) age; steepness

Question

Quizplus · Accepted Answer

The steepness and thickness of the bedrock underlying the glacier will affect the relative rates of basal slip and plastic flow, as well as the thickness of the ice. Temperature can also influence the relative rates, with colder temperatures favoring basal slip and warmer temperatures favoring plastic flow. Age is not typically a major factor in determining the relative rates of basal slip and plastic flow.
