Detailed explanation-1: -The correct answer is Glacier. The moving ice mass downslope under the impact of gravity is called a glacier. About 10% of the earth’s surface is now covered by the glacier. Glacier is formed due to the accumulation of ice above snow-line under extreme cold climate.

Detailed explanation-2: -Glaciers are masses of snow that has been compressed into giant sheets of ice. Most glaciers were formed during the last ice age.

Detailed explanation-3: -Slow-moving mass of ice or a river of ice is called a Glacier.

Detailed explanation-4: -A glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity.

Detailed explanation-5: -A glacier is any large mass of perennial ice that originates on land by the recrystallization of snow or other forms of solid precipitation and shows evidence of past or present flow.
