Answer:
The glacier have high albedos the melting of ice in summers produces a positive mechanism.
Explanation:
- Over the time period, the ice melts and this leads to exposure of the dark grey rocks and causes more melting of the mountain glacier. The reflection from glacier snow is highest as ice absorbs less sunlight and keeps the surface cooler.
- Thus reflecting back 90% of sunlight, in summer months due to the erosion agents the ice begins to move and this adds to the positive feedback mechanism that melts glaciers.
