The amazon rainforest

climate of amazon

Warm/wet all year

average temperature:26-28

annual rainfall:2000-3000

Imporatnace of amazon

300 billion trees

Contains 50% of the worlds tropical rainforest biomass

Water cycle in the amazon rainforest

Precipitation-high rainfall,50% recycled through evapotranspiration

Evapotranspiration-Huge due to vegaitation,75% intercpeted rain reuturns to atmo

Infiltration-soil is deep/porus

Runoff-reletively low due to interception/infiltration

Human impacts on amazon

Deforestation-less interception/evotranspiration,larger runoff/flooding

Evapotranspiration-less vater vapour reachesatmosphere,fewer clouds forming,rainfall reduced

carbon cycle in the amazon rainforest

-Carbon sink(stores carbon in its vegitation and soil)

-increase in c02 leads to increase productivity as vegitation is able to  access more co2

Human impacts on the carbon cycle in amazon

-Deforestation removes photosynthesis biomass so decrease in carbon uptake

-no roots holding soil togetherwill wash away top layertransferring carbon to hydrosphere
