6. how does slope affect mass movement?

Rotational slumping is a form of mass movement and occurs on coasts mainly. It involves a large area of land moving down a slope (obviously). Due to the nature of the slip, it leaves behind a curved surface. It’s very common on clay cliffs, during dry weather the clay contacts and cracks. When it rains, the water falls into the cracks and is absorbed until the rock is saturated. It weakens the rock and die to gravity, it slips down the slope on its slip plane.
