Answer 1

$\huge\underline{\mathbb\red{❥︎A}\green{N}\mathbb\blue{S}\purple{W}\mathbb\orange{E}\pink{R}}\:$

• 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.

Answer 2

Answer:

A glacier is a huge mass of ice that moves slowly over land. The term “glacier” comes from the French word glace (glah-SAY), which means ice. Glaciers are often called “rivers of ice.” Glaciers fall into two groups: alpine glaciers and ice sheets. Alpine glaciers form on mountainsides and move downward through valleys.
