Answer 1

Explanation:

1. A glacier is a perennial accumulation of ice, snow, water, rock and sediment that moves under the influence of gravity. A glacier forms when winter snowfall exceeds summer melting. ... Glaciers must have sufficient ice mass to flow under gravity. Retreating glaciers are those that melt more than they accumulate new snow.
