How does v shaped valley lead to the creation of meanders?
Answers
Answer:
Explanation:
As the river erodes downwards freeze-thaw weathering loosens material, which is moved downhill by soil creep (gravity) (b). This creates the characteristic v-shaped valley only found in the upper course of the river. It is steep sided and narrow. A meander is a bend in a river.
Answer:
The formation of a meander. As the river erodes laterally, to the right side then the left side, it forms large bends, and then horseshoe-like loops called meanders . The formation of meanders is due to both deposition and erosion and meanders gradually migrate downstream.
V shaped valley
Rivers begin high up in the mountains so they flow quickly downhill eroding the landscape vertically. As the river erodes downwards the sides of the valley are exposed to freeze-thaw weathering which loosens the rocks (some of which will fall into the river) and steepens the valley sides. .
Because the stream gradient is moderate or low, the river begins to erode the bank of its channel instead of valley walls. This eventually leads to a meandering stream across a valley floor. ... During this process, the shape of the valley changes from a V or U shaped valley into one with a broad flat valley floor.
