INDIAN GEOGRAPHY

Detailed explanation-1: -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-2: -Glacier is formed due to the accumulation of ice above snow-line under extreme cold climate.

Detailed explanation-3: -A glacier is a pile of snow and ice. In cold regions (either towards the poles or at high altitudes), more snow falls (accumulates) than melts (ablates) in the summer season. If the snowpack starts to remain over the summer months, it will gradually build up into a glacier over a period of years.

Detailed explanation-4: -Glaciers form when more snow accumulates over the year than melts during the summer. As layers of snow accumulate, the buried snow grains become more and more tightly packed and are converted to firn which subsequently metamorphoses to glacial ice as the firn recrystallizes.

Detailed explanation-5: -This process occurs on the upper part of the glacier, at higher altitudes, where more snow accumulates than is lost each year. This is called the accumulation zone, and is typically covered in snow year-round.
