Flashcards
Rising sea level and Coastal Flooding
Cards in this deck (9)
- 1What's the main cause of rising sea levels and what is the rate of sea level riseGlobal warming, global sea level is rising at a rate of 2mm per year
- 2What are the two factors from an increase in global temperature- Melting Ice
- Heating Oceans - 3Explain how melting ice would increase sea levelThe melting of ice on land causes water that's stored as ice to return to the oceans. This increases the volume of water in the oceans and causes sea level to rise
- 4Explain how heating oceans would cause a rise in sea levelIncreased global temperature causes the oceans to get warmer and expand. This increases the volume of water, causing sea level to rise.
- 5Rising sea levels will increase coastal flooding, what are the 4 categories that will be affected by this?1. Economic
2. Social
3. Environmental
4. Political - 6Outline the economic impacts1. Loss of tourism - coastal areas are popular with tourists, so closing them will lose money
2. Damage repair - repairing flood damage is expensive
3. Loss of agricultural land - seawater has a high salt content, thus reducing soil fertility - 7Outline the social impacts1. Deaths - floods will kill people
2. Water supplies - floodwater can pollute drinking water
3. Loss of housing - many people are made homeless
4. Loss of jobs - coastal industries may be shut down due to damage to equipment and buildings - 8Outline the environmental impacts1. Ecosystems affected - seawater has a high salt content, thus damaging/killing organisms in the ecosystems
2. Vegetation killed by water - the force of water uproots trees and plants
3. Increased erosion - a large volume of fast-moving water can erode lots of material - 9Outline the political impactsThe government has to make policies to reduce the impacts of future flooding. They can do things like building more or better flood defences or they can manage the use of areas that might be flooded
