- physical factors
- geology
- impermeable catchments have minimal water storage and capacity - results in rapid run-off
- permeable and porous rocks such as limestone and sandstone store rainwater and slow run-off
- relief (slopes)
- amazon basin - lowlands
- gentle relief
- water across surface (overland flow) or horizontally through the soil (throughflow) to streams and rivers
- steep catchments
- rapid runoff
- temperature
- high temp = high rates of evapotranspiration
- strong convection = high humidity + thunderstorms
- water continually cycled between land surface, trees and atmosphere by evaporation, transpiration and precipitation
- geology
- physical factors
- carbon
- physical factors
- net primary productivity
- 2500g/m2/year
- net flux of carbon rom atmosphere into green plants per unit time
- geology
- igneous + metamorphic rock - not much carbon
- western parts of basin - limestone - significant carbon store in slow water cycle
- net primary productivity
- physical factors
- water
