What is mass movement? - Internet Geography
Mass movement is the downhill movement of cliff material under the influence of gravity. There are a range of different types of mass movement. These are explored below. Cliffs formed from boulder clay, material deposited by glacial periods, are …
Cliff Retreat and Mass Movement | The Geography Site
Slumping. Slumping occurs when material moves along a curved path. The technical term is ‘rotation’ so slumping is also known as ‘rotational slip’ or ‘rotational slump’. In the photograph the path of the slump is highlighted by the red line.
Slump (geology) - Wikipedia
Slumps have several characteristic features. The cut which forms as the landmass breaks away from the slope is called the scarp and is often cliff-like and concave. In rotational slumps, the main slump block often breaks into a series of secondary slumps and associated scarps to form stair-step pattern of displaced blocks. [4]
Coastal processes - Edexcel Types of mass movements - BBC
There are four different types of mass movement. Bits of rock fall off the cliff face, usually due to freeze-thaw weathering. Saturated soil (soil filled with water) flows down a slope. Large...
Coastal Systems: How Mass Movement Affects the Coastline
Nov 5, 2016 · With rotational slumping, heavy rain is absorbed by unconsolidated material making up the cliff (often glacial till, or boulder clay). The cliff face becomes heavier and eventually it separates from the material behind at a rain-lubricated slip plane.
Describe the process of slumping - Internet Geography
Jul 5, 2020 · The soft boulder clay holds rainwater and run-off. Waves erode the base of the cliff creating a wave-cut notch. The clay becomes saturated and forms a slip plane. The weight of the saturated cliff causes it to slump. Find out more about mass movement.

Cliff collapse - Coolgeography.co.uk
Where the waves strike the cliff face. Cliffs can collapse in a number of different movements, called MASS MOVEMENTS; Slumping/Rotational slips. Here, water can build up in soils and add weight to it.
6B Mass Movement - A-LEVEL GEOGRAPHY REVISION: EDEXCEL
Slumping is facilitated by the presence of water, which adds weight (increasing the gravitational force) as well as lubricating it, reducing friction. An example of rotational slumping is at Christchurch Bay, in Barton-on-Sea, near Lymington in …

Undercutting of cliffs by the creation of wave-cut notches can lead to large falls and talus scree slopes at their base. In April 2013 there was a large blockfall in St Oswald's Bay on the South Dorset Coast where an 80 m section of chalk cliff was detached overnight.
