Glacier Movement: How Glaciers Move  The weight of overlying layers of ice and snow push down on the lower layers of the glacier.  This causes melting.

How do Glaciers affect the land? WED V17. What is a glacier? 0 A large, long-lasting mass of ice which forms on land and moves downslope because of gravity.

Glaciers. Essential Points Glaciers are flowing streams of ice Glaciers have a zone of accumulation where snowfall exceeds losses (ablation) Accumulation.
