Question Answer
Constructive Plate Boundary The plates move apart caused by convection currents diverging near the Earth's crust.
Destructive Plate Boundary The plates move towards each other where two plates converge.
Conservative Plate Boundary The plates slide past each other.
Managed Retreat Removing coastal protection of an area to allow it to flood to protect other areas along the coastline.
Salt Marshes An area of low lying coastal wet land that periodically gets flooded (often develop behind spits).
Cordgrass Grows in salt marshes because it is well suited to salt water and the tangle of roots help stabilise the mud by trapping sediment.
Lagoon An area of water dammed by a bar.
Bar A spit that grows connecting two headlands.
Weathering The breakdown of rocks where they are.
Erosion When rocks are broken down and carried away.
Corrasion (Abrasion) Eroded particles in the water scrape and rub against rock, removing small pieces.
Attrition Eroded particles in the water smash into each other and break into smaller fragments. Their edges also get rounded off as they rub together.
Solution Weak carbolic acid in sea water dissolves rock like chalk and limestone.
Hydraulic Power Waves crash against rock and compress the air in the cracks putting pressure on the rock.. Repeated compression widens the cracks and makes bits of rock break off.
Mechanical Weathering The erosion of rock due to the weather, e.g. freeze-thaw weathering.
Biological Weathering The erosion of rock caused by living plants, e.g. tree roots.
Chemical Weathering Erosion of rock caused by chemicals, e.g. acid rain.
Mass Movement Large amounts of material, earth, falling.
Landslide The collapse of rock or earth off a cliff or mountain.
Mudflow Mud sliding downhill fast causing lots of destruction.
Rotational Slip The movement of material downwards in a semi-circular direction.
Slumping The movement of loose material over a long period of time.
Headland Hard rock more resistant to erosion, e.g. chalk.
Bays Soft rock easily eroded, e.g. boulder clay.
Fetch Distance the wind has traveled.
Crest Top of a wave.
Trough Bottom of a wave.
Swash Wave washing up the beach at the angle of the dominant wind.
Backwash Water running back down the beach at a 90 degree angle.
Destructive Wave Backwash. > Swash High energy, more power - coastal erosion.
Constructive Wave Swash > Backwash Low energy - builds beaches.
Mass Tourism Tourism on a large scale to one country or region. E.g. Benidorm, Spain.
Exploration Only a small number of tourists visit the area and there are very few tourist facilities.
Involvement Local people start to provide some facilities such as B+B's and cafes.
Development The area begins to develop, advertise, and is now a recognised tourist attraction.
Consolidation Continues to grow as a resort and there is some tension between the tourists and the locals.
Stagnation The area is at its peak but is beginning to decline as facilities become run down.
Decline The area gets a bad reputation and its image suffers. People will lose jobs unless rejuvinated.
Rejuvination Measures are taken and money is spent to try and reduce the decline and to attract tourists back to the area.
