Question 1

How is a spit formed?

Answer 1

By longshore drift moving sediment along a coast until it reaches a headland and grows out towards sea

Question 2

How is a bar formed?

Answer 2

Sediment that gets dragged along by longshore drift on 2 headlands of a bay until they meet each other forming a bar. The water blocked off is called a lagoon

Question 3

Concordant coastline

Answer 3

Parallel to coast, unusual, coves, can be featureless e.g. Dorset. Usually just coastal erosion

Question 4

Discordant coastline

Answer 4

Rock layers perpendicular to coast
Headlands and bays
E,g. Bantry bay
Arch stack and stumps are found here. Landforms

Question 5

What’s a cove?

Answer 5

Form on concordante coast when erosion creates gaps through thin layers of resistant rock. Exposes less resistant rock that can erode easily into a cove shape

Question 6

Hydraulic action

Answer 6

Compression and force of water and air being forced into crack

Question 7

Abrasion

Answer 7

When rocks are picked up by waves and smash into cliff

Question 8

Solution

Answer 8

When sea becomes acidic caused by vegetation near cliff. Dissolves rock such as limestone

Question 9

Attrition

Answer 9

Rocks that are held in waves, smash into each other. Gradually rocks become smaller and smoother

Question 10

Constructive waves

Answer 10

Long wave, low her height, common in summer, low wave frequency, stronger swash, surging waves forward, adds sediment to beach

Question 11

Destructive waves

Answer 11

Short wave length, high wave height, common in winter, high wave frequency, stronger backwash, plunging waves downwards, removes sediment from beach

Question 12

Solution transport

Answer 12

Within water, dissolved, very small, chalk

Question 13

Suspension

Answer 13

Within water, carried, small

Question 14

Traction

Answer 14

Seabed, rolling, large

Question 15

Saltation

Answer 15

Seabed, hopping, large
