GEOLOGY

Detailed explanation-1: -V-shaped valleys are carved out by the river in their youthful stages. They are formed by the erosional actions of the rivers. Their shapes are of the letter of the English alphabet V. They are associated with gorges, canyons etc.

Detailed explanation-2: -A V-valley is formed by erosion from a river or stream over time. It is called a V-valley as the shape of the valley is the same as the letter “V”.

Detailed explanation-3: -Rivers begin high up in the mountains so they flow quickly downhill eroding the landscape vertically. The river cuts a deep notch down into the landscape using hydraulic action, when the sheer force of the water gets into small cracks and breaks down the sides of the river valley.

Detailed explanation-4: -V-Shaped Valleys They are formed by strong streams, which over time have cut down into the rock through a process called downcutting. These valleys form in mountainous and/or highland areas with streams in their “youthful” stage. At this stage, streams flow rapidly down steep slopes.
