Glacier:

                The temperature remains low on the areas having high altitude. Due to this, snow continues to fall there. When snow is accumulated and compressed over many years, the snow below takes the shape of thickened ice masses and begins to move downhill. It is called Glacier.

Drainage System:

                 Abundant snowfall on our mountains given rise to the gigantic glaciers. They continue melting slowly in summer and keep our rivers and streams flowing throughout the year. They are a source to provide water to our population, agriculture, and industry. Our long and unique canal irrigation system owes a great deal to these glaciers.
