"Low waves that bring sand and shingle to build up a beach."
Destructive Waves
Constructive Waves
Swash
STACK FORMATION. First, there is a opened up by hydraulic action. It eventually gets bigger and forms a by hydraulic action and . This becomes larger. Then it breaks through the headland forming a natural . This then gets eroded and collapses leaving a tall rock . This is further eroded forming a .
Long shore drift occurs in areas where prevailing winds approach at a perpendicular angle.
Tick the three man made features that are meant to prevent erosion.
Groyne
Cliff barrier
Sea Wall
Revetments
Beach defence
What is the distance that the wind blows over the sea called?
Non prevailing wind
Prevailing wind
Fetch
The stack goes through the process of erosion in the final stage of stack formation.
What is the proper geographical definition of a lagoon?
A shallow body of water, especially one separated from a sea by sandbars or coral reefs.
Salt water formed around the marsh next to an estuary
A freshwater lake formed behind a bar.
Headlands are formed when the sea attacks a section of coast with alternating bands of and rock.
Coastlines where the geology alternates between bands of hard rock and soft rock are called...?
alternating concordant and discordant coastlines
concordant coastlines
discordant coastlines
When a wave breaks, water is washed up the beach - this is called the . Then the water runs back down the beach - this is called the . With a constructive wave, the swash is than the backwash. With a destructive wave, the is stronger than the .
Tick the 2 boxes that are advantages of groynes.
Prevents the movement of beach material along the coast by longshore drift.
Protects the base of cliffs, land and buildings against erosion. Can prevent coastal flooding in some areas.
Absorb the energy of waves.
Allows the build up of a beach. Beaches are a natural defence against erosion and an attraction for tourists.
On a purely sand beach, the coarse sand will be at the top and the finest particles will be by the sea.
The water behind a spit is a .......... environment. Choose the correct answer.
high energy
low energy
no energy
The movement of eroded material up and down, and along the coast is called . When the sea loses energy, it drops the sand, rock particles and pebbles that it has been carrying and deposits them. This is called .
Abrasion is when waves cause the rocks to crash against each other, breaking them down into smaller and rounder pieces.
