how is v shaped valley formed
Answers
HEY MATE , HERE IS UR ANS
The work of a river begins from its very source , in high mountains the flow of a river is very swift as it depends the steep slopes and it exerts a great force is cutting the mountain vertically . As a result , a deep valley developes , narrow at the bottom and wide at the top this usually called a v shaped valley
Answer:
These geological formations appeared by erosion over time. In the upper course of the river, vertical erosion is more dominant compared to lateral erosion. While flowing downhill quickly, rivers remove maximum sediments from the bottom floor of the river channel than from riversides. This process is known as downcutting. It could be better understood by an example of a knife cutting through a cake.
The river in their upper course carries rocks and stones in its water. The water force and the grinding of rocks and stones carve out a valley cutting down the river bed. A valley becomes more profound and broader over time. The river gradient that is how quickly it drops determines the steepness of the sides and the floor width of the valley. The steeper the river is, the deeper the valley it creates.
The water from rain, snow and melting ice flows down the mountain to create a valley. At the mountains, this water carves down the earth below for millions of years to form valleys. The valleys in the mountains usually have near-vertical steep walls and a narrow channel, but the slopes of those valleys remain shallow, and the channel at the bottom is broader on the plains.
