Question

Define a u shape vally how it is formed​

Answer 1

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.

• U shaped valley's are formed due to frozen Rivers Called GLACIERS, when the slow moving river melts ... the upper portion flows more fast and the bottom part remains frozen .

Hence the widening of upper portion gradually forms a U shaped valley.
