earthquakes
Which is not a process of wave erosion
corrasion
hydraulic action
attrition
traction
Which statement best describes a wave
a stretch of open water
a circular movement of water
the movement of water
the undulating motion of the sea
Which is not common to rivers and waves in the removal or transportation of materials
traction
suspended load
saltation
longshore drift
The diagram shows the formation of a bay. Which best explains its formation
(i) erosion of headland
(ii) waves eroding less resistant rocks
(iii) mountain ranges submerged at right angles to the coast
(i) and (ii)
(i) and (iii)
(ii) and (iii)
(ii) only
The action of the wave in the diagram shows
swash and backwash meet together
backwash is greater than swash
swash is far greater than backwash
no obstruction between swash and backwash
Which is not a feature formed by marine erosion
beaches
spits
mudflats
bays
Constructive waves are low powerful waves that surge up the beach, their swash is more powerful than there backwash, they form from waves created by storms far out at sea
True
False
Destructive waves fit the shoreline at 10 - 14 waves per minute
True
False
The prevailing wing is also called the most common wind
True
False
In the Caribbean west facing coastlines tend to be affected by high energy waves and east facing coastlines are sheltered
True
False
Which is not a form of coastal transportation
solution
traction
saltation
attrition
Which are features formed from coastal erosion
headland and bay
caves, arches and stacks
beaches
spits and tombolo
Which are features formed from coastal deposition
headland and bay
caves, arches and stacks
beach
spit and tombolo
Select the correct sequence of the following formation
headland, cave, arch, stack
arch, headland, stack, cave
cave, arch, headland, stack
headland, cave, stack, arch
Waves that approach the coast at an angle, and move in a zig-zag pattern along the beach is called
wave refraction
longshore drift
orthogonals
wave cut platform
Which features are shown in the diagram
(i) headland
(ii) arch
(iii) stack
(iv) cave
(i) to (iv)
(ii) (iii) (iv)
(i) (iii) (iv)
(i) (ii) (iii)
A long narrow accumulation of sand or shingle with one end attached to the land and other ending in the sea is a/an
tombolo
spit
offshore bar
bayhead beach
Which feature is formed as a result of destructive ways
spits
bars
cliffs
mudflats
The feature at X in the diagram is termed a/an
spit
tombolo
bays
offshore bar
Coastal erosion is most effective when the waves are powerful and contain alot of energy
True
False
A wave cut notch develop due to hydraulic action and corrosion of a cliff
true
false
Headlands develop when rocks of the same strengthens are exposed at the coast
True
False
Deposition of sediment occurs when the velocity of water is reduced and the sediment can no longer be carried or moved by the sea
True
False
When waves are distorted by the shape of the coastline the process is called wave refraction
True
False
A narrow sand or shingle deposit that runs parallel to the coast , out at sea is called a baymouth bar
True
False
Overtime a sea cave becomes enlarged and eventually join to form an arch
True
False
When waves approach the coast at an angle, sediment moves in a zig zag pattern, this is called longshore drift
True
False
A spit is not actual land
True
False
The stronger the wind the more powerful the waves
True
False
