GENERAL GEOLOGY

Detailed explanation-1: -Glaciers are massive bodies of slowly moving ice. Glaciers form on land, and they are made up of fallen snow that gets compressed into ice over many centuries. They move slowly downward from the pull of gravity.

Detailed explanation-2: -An ice sheet is a mass of glacial ice more than 50, 000 square kilometers (19, 000 square miles). Ice sheets contain about 99% of the freshwater on Earth, and are sometimes called continental glaciers. As ice sheets extend to the coast and over the ocean, they become ice shelves.

Detailed explanation-3: -The moving ice mass downslope under the impact of gravity is called a glacier. About 10 percent 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-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: -Ice Sheets. Ice sheets are continental-scale bodies of ice. Ice Fields and Ice Caps. Ice fields and ice caps are smaller than ice sheets (less than 50, 000 sq.
