Coastal erosion - geography A level

A definition of coasts is

The seaside / beach

The narrow contact zone between land and sea

Where the salty atmosphere from the sea attacks the land

Draggable item		Corresponding Item
Destructive wave		Maximum distance wind blows over the sea
Fetch		The incoming wave, comes in at the same angle the wind blows
Swash		The wave that returns to the sea, always at 90 degrees due to gravity
Backwash		Builds up the beach as the swash has energy to bring in sediment, but the backwash is weak so it gets left behind.
Contructive wave		Removes sediment from a beach as the backwash is strong enough to entrain particles and return them to the sea.
