Question

Glaciers do not form deep narrow valleys why valleys

Answer 1

Dear student,

Please find below the solution to the asked query.

The glacier can alter as well as  totally remove the existing landforms ,creating completely and new and different landforms.

U shaped valley-When a glacier passes through valley ,the floor and sides of valley are eroded by the rock pieces present in the glacier.Thus, the floor becomes flat and sides become steep .This type of valley is called U-Shaped valley.

Crique- Along the slope of a mountain ,the glacier carves out deep hollows .It develops an armchair like depression which is known as crique.

Tarn-The depression is filled up with water and forms a lake when glacial ice meets .This lake is known as tarn.

Glacial moraines-The capacity of glacier to carry load is reduced when it starts melting .Hence in deposits the rock material on the floor and side of the valley .The deposits form glacial moraines.
