|
Overview |
- South America 6km2 - 70% of the Rainforest is in Brazil - Largest Forest, Tall Evergreen, Hardwood Trees |
|
|
Water Cycle Features |
- High average temperatures 25C and 30C - Hardly any variations in temperature - High average annual rainfall (2000mm) and no dry season |
|
|
Water Cycle Factors |
- Insolation by clouds leading to stable and consistent temperatures - 50-60% of precipitation is recycled by evapotranspiration |
|
|
Precipitation |
- 2000mm distributed evenly throughout the year - High intensity convectional rainfall - Intercepted rainfall 25% |
|
|
Evapotranspiration |
- High temperature causes lots of evapotranspiration - High moisture and dense vegetation - Most evaporation caused by interception |
|
|
Run off |
- Rapid run off and well drained soils - River discharge peaks 1-2 a year |
|
|
Atmosphere |
- High temperature allows the storage of lots of moisture - Relative and absolute humidity is high |
|
|
Carbon Cycle |
- Rapid decomposition of dead matter - Carbon fixation due to photosynthesis is high - Soils hardly store carbon and roots take up 95% of the nutrients rapidly - Soils simply allow water and nutrients to flow in and out very quickly |
|
|
NPP & Biomass |
- High productivity and temperature 2500g/m2/year
- Biomass 700 tonnes/ha - Largest trees store 180 tonnes C/ha - Below ground holding 40 tonnes C/ha - The Amazon rainforest stores 2.4 billion tonnes of carbon |
