|
What are the 4 interacting systems? |
Atmosphere Biosphere Lithosphere Hydrosphere |
|
|
Natural resources that are non-renewable? |
Oils and minerals |
|
|
What are renewable resources? Examples? |
Resources that if carefully managed, can be replenished or regenerated: forest, soil and fresh water |
|
|
Examples of inexhaustible resources? |
Energy from tides, wind and sun - as long as Earth's systems still function these will never deplete |
|
|
What is the biggest contributor of greenhouse gases to the atmosphere? |
Burning of fossil fuels |
|
|
Major impacts of climate change to alpine regions? |
Predicted to shift to higher altitudes impacting upon the size and biodiversity of these regions |
|
|
What effects will climate change have had in the next 10 years? |
Malawi: droughts Vietnam: threatened by rising sea levels Bangladesh: flooding Sudan: food deficiency from the impact of climate change on agriculture Philippines: frequent and more intense storms |
|
|
What effects will climate change have had in the next 20 years? |
By 2040 most of Europe will be Saharan and parts of London will be underwater |
|
|
What are some points of proof climate change is happening? |
- decrease in duration of ice cover - decrease in sea ice extent and thickness - plan and animal biodiversity lessened - decrease in permafrost and snow cover - coral reef bleaching - flowering and migration |
|
|
What is the carbon cycle? |
The basic building blocks of life. Carbon constantly absorbed and released around the atmosphere, land and oceans. Plant releases carbon --> animal absorbs = travelling from biosphere to atmosphere |
|
|
Can low or high water temperatures hold more carbon? |
Low |
|
|
3 points about the Troposphere? |
- most important layer of Earth - where all life is found - extends approx 17km above Earth's surface - air pressure is highests here and drops as altitude rises |
|
|
3 points about the Stratosphere? |
- 17-50km above sea level - most of Ozone layer found here that keeps 95% of the suns UV rays from Earth - heat gets trapped in the fewer particles and slowly released --> higher temperatures |
|
|
3 points about the Mesosphere? |
- 50-80km above the Earth's surface - temperature decreases with height - waves and tides carry energy from Troposphere and Stratosphere into Mesosphere - driving most of global circulation |
