Question

What is a glacier?

Answer 1

1. A glacier is a large mass of ice that moves slowly over the land, from its place of accumulation. It is also known as ‘River of ice’.
2. The place of accumulation is called snowfield.
3. The height above which there is a permanent snow cover in the higher altitude or latitude is called snowline.
4. The gradual transformation of snow into granular ice is called ‘fim’ or ‘neve’ and finally, it becomes solid glacial ice.
5. The large mass of ice creates pressure at its bottom and generates heat. Due to this, the glacier melts a little and starts to move.
