the sea

Question 1

coastal process erosion 1.hydraulic action 2.Compressed air 3.Abraision 4.Attrition 5.solution

Answer 1

1.the force of waves removes removes rocks and sand from coastline 2.incoming waves compress air into joints and when the wave retreats the air expands and overtime this shatters the rock 3. pebbles are dashed along the coastline by waves which breaks off pieces of rock from the coast 4. pebbles and stones are worn down by rubbing against each other and are eventually turned into sand 5. seawater diddolves coastline

Question 2

transportation longshore drift

Answer 2

when the waves come at the shore at an angle and the swash carry the sediments up shore while the backswash carries them back down the shore at a angle

Question 3

features cliffs and waves - cut platforms

Answer 3

destructive waves erode the coast at a cliff and undermine it by eroding it forming a notch and overtime as the notch gets bigger the rocks above collapse

Question 4

bays and headlands

Answer 4

they form in ares that have hard and soft rock facing the sea the soft rock quickly gets eroded this leaves a indent in the coast which is known as a bay the hard rock is left jutting out at the sea which is called a headlind

Question 5

human interactions 1. groynes

Answer 5

groins are walls that are built to stop longshore drift to build a beach but than further up the coast isn’t getting that much sand

Question 6

rock armour/borders

Answer 6

boulders are placed at the base of cliffs so waves can’t undermine cliffs because when a wave hits the boulders take all the force

Question 7

sea wall

Answer 7

thy are built to protect coastal towns from the sea the walls are normally curved at the top forcing them to break back on top of the next incoming wave

Question 8

gabion

Answer 8

are cages with big stones in them that are placed at the front of sand dunes to reduce the power of the waves
