Beaches - Which statements are correct?
Beaches are accumulations of sand and shingle formed by deposition.
Sandy beaches can support steeper slopes than shingle beaches.
Shingle beaches can support steeper slopes than sandy beaches.
Beaches are accumulations of sand and shingle formed by erosion.
The most accurate description of a spit:
An accumulation of sand and/or shingle formed by deposition.
A cliff that juts out in the sea; it is surrounded by water on three sides.
A narrow ridge of sand and/or shingle that is attached to the mainland at one end.
A narrow ridge of sand and/or shingle stretching between two headlands, with a lagoon on the landward side.
Longshore drift
Choose the statements which apply most appropriately to this process.
This is the process of erosion which moves sand and pebbles along the coast.
Material is moved along the coast in a zigzag way.
The backwash moves sediment straight back down the beach due to gravity.
Prevailing winds bring waves in at an angle to the coast.
Why are constructive waves responsible for building up beaches?
Shingle beaches can support steeper slopes.
The backwash is stronger than the swash.
The swash is stronger than the backwash.
Typical features on or close to a spit:
Sand dunes
Curved end
Salt marshes
Wave cut notch
Conditions required for a spit to form:
Material is transported along the coast by longshore drift.
When wave crests arrive parallel to the coastline.
There is a bend in the coastline or a river mouth occurs.
A plentiful supply of sediment.
Possible reasons for a curved spit:
Wave refraction causes waves to bend and push sediment inland.
The area behind the spit is sheltered leading to the deposition of silt and mud.
Short-term change in the direction of the wind and waves.
Which landform fits the following description?
A ridge of sand and/or shingle, which has joined two headlands cutting off a bay.
Beach
Spit
Bar
Lagoon

Headlands and bays are most likely to be formed along which type of coast?
Discordant coasts
Coasts with impermeable rock
Concordant coasts
Coast with permeable rock
How do groynes work to protect the coastline?
They trap sediment by slowing down longshore drift, thereby building up a wide beach
They absorb wave energy so that the cliffs behind are protected
They act as a hard rock barrier at foot of cliff to provide a buffer again the sea
They allow rapid longshore drift along the coastline
If the photo is facing south, which direction is longshore drift working in?
