Questão | Responda |
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. |
