Answer to Question 1

C

Answer to Question 2

Rates of movement of glacial ice vary considerably. Some ice sheets move slowly enough that vegetation is able to establish itself within the debris carried on the ice sheet (e.g., rates of less than 2 meters per year). Other glaciers advance several meters per day (e.g., over 800 meters per year). Some glaciers experience surges, which are occasional periods of extremely rapid advance.
