Sentences describing Antarctic glacier scenery

The sentence describing the scenery of Antarctic glaciers is as follows:

Glacier is a huge flowing solid, which is formed by recrystallization and accumulation of snow in alpine regions. Glaciers are distributed in mountainous areas from the poles to the equatorial belt. It is the largest fresh water resource on the earth and the largest natural reservoir except the ocean, and its fresh water accounts for about 69% of the earth's fresh water.

Glacier is a kind of natural ice body with certain shape and movement, which exists in the cold region of the earth for a long time and is formed by the continuous accumulation and deterioration of snowfall for many years. Glaciers are different from natural or artificial frozen ice. They can slide down a specific terrain under their own gravity.

Glacier is a form of water, which is transformed from snow through a series of changes. To form glaciers, there must be a certain amount of solid precipitation, including snow, fog, hail and so on. Without enough solid deposits as "raw materials", it is equal to "cooking without rice" and it is impossible to form glaciers.

On high mountains, glaciers can form. The mountain should not be too steep except at a certain altitude. If the mountain peak is too steep, the falling snow will fall down the slope and will not form snow, so it is impossible to form a glacier. Snowflakes change as soon as they fall to the ground. With the change of external conditions and time, snowflakes will become spherical snow that completely loses its crystal characteristics, which is called granular snow. This kind of snow is the raw material of glaciers.
