Question

What are the basic differences between glacial valleys and river valleys?

Answer 1

Glacial and River valleys can be differentiated based on the following parametersFormationGlacial valleys are formed due to the movement of glaciers and the abrasion of the rock particles they carry. The formation of glacial valleys does not depend on the gradient but only the volume of the glacier. Larger glaciers carve larger, wider valleysRiver valleys are formed due to the kinetic energy of rivers falling from a steep height. The formation of the valley is dependent on the gradient as rivers carry less water during their youthful stagesShape of the valleyGlacial valleys are usually U-shaped . They are wide.River valleys are V- shaped. They are deeperTime of formationMost of the glacial valleys seen today were formed during ice age (Pleistocene era) . Glacial valleys can also be seen near mountain ranges where the glaciers have recededRiver valleys are recent formationsExamplesGlacial valleys : Yosemite (USA, Image below), The Frades Valley (Brazil), Glacier National Park, Montana (USA), Calchaquí Valleys (Argentina)River Valleys : Indus Valley (Pakistan) , Kashmir Valley (India) , Doon Valley ( India, Image below) .

Answer 2

Valleys are the one of the most important geographical landforms in any region.

There are many types of valleys according to their geographical characteristics difference.

Glacial valley:

This type of valleys are formed due to the glaciation process and this valleys ar "U" in shape.

On the other hand;

River valley:

This landforms are actually drained by a complete river system and this type of valleys are naturally enriched.
