slumps often occur in saturated conditions
the difference between sliding and slumping is that there's a rotational movement in slumping
slumps occur on moderate to steep slopes
involves a large area of land moving down the slope in one piece
Usually found on weaker rock types (i.e. clay), that become saturated and heavy
they're common where softer materials e.g clays and sands overlie more-resistant or impermeable rock such as granite or limestone
slumping causes rotational scars
repeated slumping creates a terraced cliff profile
