उत्तर
- 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’.
- The place of accumulation is called snowfield.
- The height above which there is a permanent snow cover in the higher altitude or latitude is called snowline.
- The gradual transformation of snow into granular ice is called ‘fim’ or ‘neve’ and finally, it becomes solid glacial ice.
- 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.
