the work of the sea

• comression
• attrition
• abrasion
• hydraulic action

the wind blows across the surface of the water

• sea cliff
• bay
• headland
• sea cave
• sea arch
• sea stack
• blow hole

Air trapped by the waves causes the rock to shatter

the force of the water bashing against

Is when rocks and stones hit and rub off eachother and create sand and pebbles

Is when rocks and stones carried by the sea crash against the coast

• sea cliffs are formed by hydraulic action. As the waves pound against the coast a cut is formed.As the cut gets the overhanging rock becomes unstable and collapses to form a cliff
• E.g
• The Cliffs of Moher,Co.Clare

• a bay is a wide curved opening into the coast. It is formed where areas of hard rock and soft rock lie side by side.The soft rock erodes faster to form a bay shape.Sandy beaches are often found on the inside of bays.
• E.G
• Donegal bay

A headland is formed in the same way as a bay only that it is hard, resistant rock that is left behind that makes up a headland . Its a piece of land that juts further out into the sea than the land around is a headland

Its a long tunnel shape on a sea cliff. It gets lower and narrower the further into the cave it goes. Waves find a weak spot at the base of the cliff and gradually erodes it until a cave is formed
