Answer to Question 1

Answer: Glaciers form in climates cold enough that snow recrystallizes into ice. As snow accumulates, the underlying ice thickens until it becomes so heavy that the forces of gravity cause the glacier to move downslope. Glaciers move by a combination of basal sliding and plastic flow.

Answer to Question 2

Answer: When accumulation exceeds ablation, the glacier advancesit grows.
When ablation exceeds accumulation, the glacier retreatsit shrinks.
