0
Q
At what rate is sea level rising?
A
2mm per year.
1
Q
Why is sea level rising?
A
Global warming
2
Q
What two effects does global warming/ sea level rising have?
A
- Melting ice
- Heating oceans
3
Q
What happens when the ice on the land melts?
A
- The melting of ice on land (Antarctic ice sheet) causes water that is stores as ice to return to the oceans
- This increases the volume of water
4
Q
What happens when the oceans are heated?
A
- Increased global temperatures causes the oceans to get warned and expand, this increases the volume of water causing the sea level to rise.
5
Q
What will rising sea level increase?
A
Coastal flooding.
6
Q
Give 3 economic impacts of rising sea level.
A
- Loss of tourism. Many costal areas area popular tourist destinations. Flooding can cause tourist attractions to close and can put people off visiting.
- Damage repair. Flood damage can be extremely expensive
- Loss of agricultural land. Seawater reduces soil fertility so crop production can be affected for years.
7
Q
Give 4 social impacts of costal flooding.
A
- Deaths. Floods have killed thousand of people
- Water supplies affected. Floodwater an pollute drinking water with salt or sewage.
- Loss of housing.
- Loss of jobs. Industries Sh dear down due to damage.
8
Q
Give three environmental impacts of flooding.
A
- Ecosystem affected. Seawater can kill organisms in a ecosystem
- Vegetation killed as the force of the water uproots frees and plants and some are drowned
- Increased erosion because large movement of fast moving water can erode lots of material
9
Q
Give a political effect of flooding.
A
- The government make policies to reduce the impacts of future flooding. They do this by bulging more or better defences and manage areas that get flooded often such as stopping people living there.
