Coastal Landforms

Question 1

What is a landform

Answer 1

An individual coastal feature is a landform e.g cave

Question 2

What is a geo

Answer 2

A geo or gio is an inlet, a gully or a narrow and deep cleft in the face of a cliff

Question 3

how is a geo formed

Answer 3

they are created by waves eroding along faults/joints in a cliff, which cuts into the cliff

Question 4

what is a dalmatian coast

Answer 4

A dalmation coastline is formed where the geology creates valleys parallel to the coast so that when sea level rises, a series of elongated islands remain offshore.

Question 5

what is a ria

Answer 5

former river valleys drowned by rising sea levels

Question 6

what is a tombolo

Answer 6

A tombolo is formed when a spit connects the mainland coast to an island

Question 7

what is an offshore bar

Answer 7

Offshore bars are elongated ridges and mounds of sand or gravel deposited beyond a shoreline by currents and waves.

Question 8

what is a fjord

Answer 8

former glacial valleys drowned by rising sea levels

Question 9

what is a cuspate foreland

Answer 9

a triangular extension of a shoreline

Question 10

how is a cuspate foreland created

Answer 10

created by the deposition of longshore drift

Question 11

how are offshore bars formed

Answer 11

They form from sediment eroded by destructive waves and carried seawards by backwash.

Question 12

what is a raised beach

Answer 12

areas of previous wave cut platforms and the beaches connected , that are at a higher level than the sea level

Question 13

what is a baymouth

Answer 13

It is a sandbank that partially or completely closes access to a bay.

Question 14

how is a baymouth bar formed

Answer 14

by deposition of longshore drift

Question 15

what is a salt marsh

Answer 15

Salt marshes are coastal wetlands that are flooded and drained by salt water brought in by the tides

Question 16

what is a mudflat

Answer 16

coastal wetlands that are in the intertidal area where sediment like silt and clays have been deposited by tides or rivers

Question 17

what is a barrier beach

Answer 17

Barrier Beaches are narrow and elongate beaches situated parallel to the shoreline

Question 18

how is a barrier beach created

Answer 18

Barrier beaches are formed where spits are joined to the mainland at both ends, trapping water behind in a lagoon

Question 19

what is a barrier island

Answer 19

a long broad sandy island lying parallel to a shore that is built up by the action of waves, currents, and winds and that protects the shore from the effects of the ocean, not connected to the shoreline

Question 20

what is a wave-cut (marine) platform

Answer 20

a gently sloping , mostly smooth platform created by the retreat of a cliff when the base has been eroded and therefore the cliff top has collapsed repeatedly

Question 21

what is a wave cut notch

Answer 21

A wave cut notch is a natural landform caused when the original rock is eroded where the sea level is(cliff foot)

Question 22

where are landforms effected by erosion found

Answer 22

high energy coastlines

Question 23

where are landforms effected by deposition found

Answer 23

low energy coastlines

Question 24

how is a bay formed

Answer 24

a bay is formed when areas of softer rocks e.g clay , on a coastline is eroded away

Question 25

what is a bay

Answer 25

bay is an inlet of the sea where the land curves inwards, usually with a beach.

Question 26

what is a headland

Answer 26

a section of harder , more resistant rock jutting out to sea

Question 27

what are 7 main erosional landforms

Answer 27

stack, arch, cave, stump, wave-cut platform, headland, bay
