Answer 1

Answer:

Hi....

Thanks for your question...

Explanation:

Answer -1

Due to constant deposition of river sediments on the slower side and the vast amount of erosion that takes place on the faster side. This process keeps on continuing till the curves get sharpened, so that river cuts through the curve and forms another path and thus river changes its course.

Answer -2

Over a period of time, rivers tend to change their course due to the rocks present at the shores. ... The speed of the flow of the river is changed due to the obstruction in the river bed. This further gives rise to the meandering process, wherein the river flows faster, there will be less sediment deposition.
