Give a geographical reason:
Snowline decides the limit of glacier work as an agent of erosion.
Snowline decides the limit of glacier work as an agent of erosion because -
- Snowline is the lower limit of permanent snow cover; below which snow does not accumulate.
- The glacier moves through the pre-existing valley and forms erosive action.
- The glacier performs plucking and abrasion processes on the rocks on its way.
- Below the snowline is the snow frees surface, where the erosional features are not formed.
Concept: Agents of Erosion and Landforms - Work of Glacier
