Question

Give a geographical reason:

The snowline is retreating.

Answer 1

The snowline is retreating because -

1. A snowline is a boundary between a snow-covered and snow-free surface. Above the snowline, there is permanent snow cover.
2. When glaciers and icebergs melt at an alarming rate, it is a cause of concern. This is known as retreating glaciers.
3. Due to changes in the climate, there is less snowfall as compared to the previous years.
4. This means that there is lesser ice formation each year than its rate of melting.
5. Thus, due to the melting of glaciers and icebergs as well as less snowfall the snowline is retreating.
