Hi guys. I am Aarish and our lesson today is about glaciers
GLACIERS :
A glacier is a huge block of ice that flows very slowly over land. Glaciers are formed in the North Pole and South Pole and in high mountains 🏔️. The cold climate and low temperatures in these areas help large amounts of ice to collect and turn into ice blocks.
Glaciers begin to form when more snow falls during the winter months than it evaporates in the summer months. The snow builds up in layers and these layers get heavy because of their weight. Gradually, the ice becomes so thick that it begins to move because of its own weight and starts to move down the mountains 🏔️. This happens due to the Law of Gravity. As they move down the slopes of mountains they melt very slowly, getting heat from the Earth.
As glaciers move downwards, they also change the shape of land they move on. Most glaciers flow extremely slow and move less than 30 centimetres a day. But some glaciers can flow up to 15 centimetres a day. The various parts of a glacier move at different speed. The central and upper part of a glacier flows the fastest. The sides and bottom move more slowly because they rub against the walls and floor of the valley.
World's most famous glaciers are in Europe. They lie in the French and Swiss Alps. They are Mer de Glace and the Aletsch Glacier.
