strip cropping

Lakes which are made by residual rocks which are left after weathering and erosion and form the residual lakes.

A residual haunting is a playback of a past event.

When the process of erosion takes place gigantic wave of water flows on the mountains and other highland areas this causes boulders, sediments and other solid materials are washed away and when these rocks re-situated in a large size on other parts of land then called residual hills. We can also say that they hard rocks left behind after erosion are then called residual hills.
