Multi-Use Area
An area along the coast that has many different uses e.g. shipping, tourism, surfing, beach etc.
1 of 26
Infrastructure
The basic physical and organizational structures and facilities (e.g. buildings, roads, power supplies) needed for the operation of a society or enterprise.
2 of 26
Swash
Movement of waves UP a beach
3 of 26
Back Wash
Movement of water DOWN a beach
4 of 26
Marine Erosion
The wearing away of rock, by the action of the sea.
5 of 26
Erosion
The wearing away of rock, stones or soil by rivers, waves, glaciers or wind.
6 of 26
Transportation
The material is carried away.
7 of 26
Deposition
When the material is dropped off
8 of 26
Hydraulic Pressure
The waves FORCE water into cracks in the rocks.
9 of 26
Attrition
The waves knock chunks of rock together. The rocks end up as pebbles on the beach.
10 of 26
Solution
The water DISSOLVES soluble material from the rocks.
11 of 26
Abrasion
Rough seas fling pebbles against the rocks. The pebbles act like sandpaper.
12 of 26
Sub Ariel Process
Process that attack the face and top of a cliff.
13 of 26
Weathering
The breaking down of rocks by the action of the weather, plants or chemical actions.
14 of 26
Corrosion
Sea water is very corrosive and can slowly dissolve chalk and limestones, increasing the size of cracks and joints so that the forces of erosion are more effective.
15 of 26
Wetting/Drying
Softer rocks e.g. clay expand when wet and contract when they dry out. This continued expansion and contraction can weaken rocks making them more easily eroded.
16 of 26
Mass Movement
Rockfalls are a sudden type of mass movement. Rocks like clay become saturated with water becoming weaker. This causes mudflows (a type of massmovement).
17 of 26
Slumping
The rapid downward movement of a large quantity of saturated earth.
18 of 26
Slipping Plane
A line of weakness, often where a previous landslide has occured.
19 of 26
Landslide
A movement of a mass of rock, earth of debris down a slope.
20 of 26
Mudslide
Involves a whole segment of the cliff moving down slope along a saturated shear-plane.
21 of 26
Soft Coastlines
Coastlines that are less ressisstant rock e.g. clay and the rates of erosion are very quick. Weathering increases the rate of erosion making the rocks weaker causing them to be unpredictable.
22 of 26
Eco system
Communities of plants and animals within a particular physical enviornment.
23 of 26
Reef
Ridges of rocks near the surface of the sea.
24 of 26
Sedimentation
Deposition of fine sand.
25 of 26
Managed Retreat
The process of some land allowed to flood and this means the water can sread out. Marshes may develop and trees may grow.
