Question

2) U shaped valley and V shaped valley​

Answer 1

Answer:

U-shaped valleys, trough valleys or glacial troughs, are formed by the process of glaciation.

V-shaped valleys are even more common because they are usually eroded by running water. This is not an exhaustive classification. There are more valley types. Tectonic valleys, for example, are formed by entirely different forces.

Answer 2

$\huge \bold{ \red{ \underline{ \underline{Answer}} \: }}$

Definition: U-shaped valleys form through glacial erosion. Glaciation develops in established v-shaped river valleys where the ice erodes the surrounding rocks to create a “U” shaped valley with a flat bottom and steep sides. Glacier movement is driven by gravity.
