headland
is a part of the shore that sticks out into the ocean.
erosion by waves
Waves shape the coast through erosion by breaking down rock and moving sand and other sediment.
wave energy
Large waves can hit rocks with grate force. This energy in waves can break apart rocks. Over time, waves can make samll tracks larger.
abrasion
Process occurs when waves carrying sediment wear away rocks along a coast.
beach
Is an área of wave washed sediment along a coast.
Landforms created by wave erosion
Waves can hit a rocky coast erode the base of the land there. Where the rock is softer, the waves rodee the land faster
sea cave
is a hollow área in the rock which waves have eroded.
Deposit by waves
Deposit occurs when waves slow down, causing the water to drop its sediment.
Coast shape
Waves shape a coast when they deposit sediment, forming coastal feautures such as beaches, sandbars, barrier beaches and spoits.
longshore drift
Process by which beach sediment moves down the beach with the current.
sandbars
They are fronde when the incoming waves carrying sand build up sandbars.
barrier beach
is similar to a sandbar. It is formed when storm waves pile up large amounts of sand above sea level, forming a long, narrow island paralelo to the cost.
Spit
is a beach that projects like a finger out into the water.
Erosion by waves
Waves shape the coast through erosion by breaking down rock and moving sand and other sediment.
Impact
Is one way waves erode the land.
Fast erode
When coastal rock is softer
Why waves change direction_
as they aproach shore because they begin to drag.
headlands
Is the landform where waves approach to the shore and change direction and ismore of their energy concentrated.
sea arch
Is a coastal feature formed by wave erosion.
When waves speed up?
