Solution
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-free surface, where the erosional features are not formed.
