Albedo
What is Climate change?
A large-scale, long-term shift in Earth’s weather patterns or
average temperatures. Encompasses global warming.
Biome found at 30 degrees latitude
Hot desert
Biome found at 0 degrees latitude
Tropical rainforest
Biome found at 60 degrees latitude
Temperate forest
Biome found at 90 degrees latitude
Tundra (cold, dry)
Natural Climate Change (3 types)
- Cosmic changes (Milankovitch cycles)
- Solar/Sun spot activities
- Volcanic activity
Name a cause of anthropogenic (man-made) climate change
Burning of fossil fuels for industry, transport, domestic use.
-This releases gases such as CO2, SO2 and NO2
Umbrella term for gases that trap solar radiation in the atmosphere
Greenhouse Gases
The type of air cell that moves between 0 and 30 degrees latitude?
Hadley Cells
Describe the temperature and movement of air in a Hadley Cell?
- Hot air rises at 0 degrees - causes low pressure
- Cool air sinks at 30 degrees - causes high pressure
The type of air cell that moves between 30 and 60 degrees latitude?
Ferrel Cells
Describe the temperature and movement of air in a Ferrel Cell?
- Cool air sinks at 30 degrees - causes high pressure
- Hot air rises at 60 degrees - causes low pressure
At high pressure is there low or high rainfall?
Low precipitation (remember high and dry)
At low pressure is there low or high rainfall
High precipitation
