1.1 - Coasts

Question 1

Weathering

Answer 1

The break down of rocks and minerals on the surface

Question 2

Littoral Zone

Answer 2

Area of shoreline where land is subject to wave action.

Question 3

Backshore

Answer 3

Area above high tide mark, only affected by waves during major storm events.

Question 4

Nearshore

Answer 4

Area of shallow water beyond tide mark, friction between the wave and seabed cause the wave to distort and crash down here.

Question 5

Foreshore

Answer 5

Where the ride comes in and out.

Question 6

Offshore

Answer 6

Area of deeper water beyond the point where waves break. Friction between waves and seabed cause distortion of waveshape.

Question 7

Dynamic Equilibrium

Answer 7

Nothing in this area can change anymore

Question 8

Dynamic Zone

Answer 8

Long-term changes = sea level variation due to climate change. ST Changes = high and low tide and wave energy due to weather conditions.

Question 9

Rocky, Cliff Coastline

Answer 9

High relief
High energy

Question 10

Estuartine Coastline r

Answer 10

Low relief
They form river mouths deposition>erosion, low energy environment and less resistant rock.

Question 11

Sandy Coastline

Answer 11

Low relief
Low coastline

Question 12

Estuartine Coastline

Answer 12

Where a body of water is surrounded by land but open to the sea on one side, rivers flow into this.

Question 13

Relief

Answer 13

Resistance

Question 14

Sediment Systems

Answer 14

Material is eroded, transported along and deposited elsewhere.

Question 15

Coastal Plains

Answer 15

Land gradually slopes
Deposited sediments

Question 16

Secondary Coasts

Answer 16

Dominated by marine erosion/deposition e.g. Slapton

Question 17

Primary Coasts

Answer 17

Dominated by land-based processes e.g. river deposition
