What is fall?
rapid form of mass movement
Blocks of rock a an be dislodged by mechanical weathering
Wave cut notches can cause large falls
Scars and scree are left
Talus scree slopes have irregular sized particles
What is topple?
verticals dip causes it
Water from rain can cause weakness and eventually toppling
Wave cut notches and undercutting will cause instability and toppling
What is a translational slide?
its low angle seaward dip prevents falls
Material slides down the slope into the sea
It slides down a glide plane to the impact point where it turns into debris in the sea
Causes a terraced cliff profile
What is a rotational slide/slump
occurs along a curved, failed surface
Water saturated cliffs slide and rotate downslope from days to years
Prompted by pore water pressure
Causes a rotational scar
What is flow?
common in weak rocks such as clay or unconsolidated sand
They becoming saturated, losing their cohesion and flow downslope
Heavy rainfall and high tides can contribute to the saturation
