Deposition

Answer 1

Question 2

Long shore drift

Answer 2

The transportation of material along a coastline by waves

Question 3

Headland

Answer 3

A piece of land that juts out into the sea

Question 4

Bay

Answer 4

A broad coastal inlet often with a beach

Question 5

Discordant

Answer 5

Where rocks are at right angles to the sea

Question 6

Hydraulic action

Answer 6

The power of the eaves puts pressure on the cracks in the cliff

Question 7

Abrasion

Answer 7

Rocks in the sea scrape along a cliff like sandpaper or smash into a cliff

Question 8

Attrition

Answer 8

Where rocks hit each other in the sea and get smaller

Question 9

Solution

Answer 9

Where there is a chemical reaction between the water and rock. The rock dissolves.

Question 10

Fetch

Answer 10

The distance over which the wind has blown

Question 11

Prevailing wind

Answer 11

Main direction where the wind comes from

Question 12

Subaerial processes

Answer 12

The processes of weathering affecting the cliff area

Question 13

Overhang

Answer 13

Where the soft rock erodes much quicker than the hard rock which is above it

Question 14

Concordant

Answer 14

Where the rocks are parallel to the sea

Question 15

Stack

Answer 15

A column of rock in the sea near a coast, formed by wave erosion

Question 16

Stump

Answer 16

When erosion caused the stack to collapse, leaving a smaller version of a stack (a stump).

Question 17

Destructive wave

Answer 17

They are big strong waves that usually have travelled over a long fetch. They have a stronger backwash than smash.

Question 18

Constructive wave

Answer 18

They are small low waves that are less powerful than destructive waves. They have a stronger smash than backwash.

Question 19

Coast

Answer 19

The land along he sea

Question 20

Coastline

Answer 20

The boundary of a coast, where the land meets the water.

Question 21

Wave cut platform

Answer 21

Occurs when the hard rock falls down (multiple times) due to no soft rock beneath it to support it. A wave cut platform is the rock which lays at the bottom of the sea bed

Question 22

Groynes

Answer 22

Timber or rock that juts out into the sea and traps sediment from being moved down the coast by long shore drift.

Question 23

Beach nourishment

Answer 23

Sand pushed onto the beach

Question 24

Rock armour

Answer 24

Piles of large boulders dumped at the fort of cliffs, forcing waves to break, protecting the cliffs from eroding back as quickly.

Question 25

Gabions

Answer 25

Small rocks in cages which are built into the cliff surface. Hard engineering.
