Snowline decides the limit of glacier work as an agent of erosion : give reason

Answer 1

Explanation:

Snowline decides the limit of glacier work as an agent of erosion : give reason?

$\huge\blue{Answer}$

The hydrosphere, liquid water, is the single most important agent of erosion and deposition. ... Maximum extent of Laurentide Ice Sheet .... The glacial budget works in a similar way.

Answer 2

Answer:

The snowline is defined as the transition zone (line) that lies between the snow-covered areas and the snow-free areas. This means that the area that lies above this line will be comprised of ice and glaciers, whereas the areas that lie below the line will be comprised of rocks and materials that do not contain ice over them.

These ice and glaciers that are present above this snowline are responsible for the formation of erosional structures such as horns, aretes, hanging valleys as the ice or glaciers flows over the surface along an inclined or curved plane. This glacial erosion does not take place below the snowline as the snow melts below this line.

Thus, the snowline controls the glacial erosion that takes place in the high mountains.
