Mass Movement
Mass movement encompasses the gravitational movement of rock, soil, and sediment down slopes. Types include rockfalls, slides, flows, and complex failures, occurring on coastal cliffs and inland slopes.
Real World
In 2008, a major rotational slump at Holbeck Hall Hotel in Scarborough caused the building to collapse into the sea after prolonged rainfall saturated the boulder clay cliff, increasing pore water pressure and triggering slope failure.
Exam Focus
Identify the specific mass movement type (rockfall, slump, mudflow) and link it to a named trigger such as rainfall.
