Geography: Coasts Revision
Key words
Weathering: the decomposition and disintegration of rock material in situ (its original
place) Erosion: the wearing away and removal of material by a moving force Mass
movement: Removal of cliff-face material under influence of gravity (e.g. Rock
falls/slides/ slumping) Wave: ridge of water formed by…

- E.g. Soft clay in Studland Bay has eroded, but not hard chalk of the Foreland
Wave-cut notches, wave-cut platforms - Wave-cut notches formed by hydraulic action,
abrasion and corrosion to base of cliff by
destructive waves - Cliff no support collapses cliff retreat slope called
wave-cut platform is formed…

Depositional landforms - Formed when material builds up faster than waves can move
them away. Waves are
constructive (stronger swash than backwash). Destructive waves erode material so
provide sediment for deposition - Spit- formed by material transported by LSD to the
end of the beach in areas where coastline changes…

Hard rock Soft rock
Shape of cliffs
Cliff face
Foot of cliff
High, steep Lower, less steep
Rugged bare rock Smoother rock, evidence of slumping
Boulders, rocks Sand, mud, few rocks
Vegetation - Must be adapted to saline conditions - Preserve and protect coastal
landforms (see: Coral reefs, mangroves)
Sea-level…
