Temperature is consistent all year round, the forest has a low latitude with high rainfall.
Geology- impermeable rock, water can't infiltrate making movement between stores rapid.
Relief- extensive low lands. In the west the Andes create a steep catchment with rapid run off.
Temperature- high temperatures with fast evaporation.
Since 1970 1/5 of the primary rain forest has been destroyed.
Water cycle- 2000-2012 30,000 km^2 deforested. Madeira river flooded in April 2004 causing 60 deaths and a cholera outbreak.
Carbon cycle- 60% of the carbon in the Amazon is stored in trees, due to deforestation large amounts of carbon are being released.
8/9 months= negative heat balance, low biodiversity. Growing season= 3 months
Water cycle Carbon cycle
Generally Low precipitation (200mm/year) More carbon released in summer as the
Permaforst limits infiltration active layer thaws
Physical Winter= water stored as ice Most carbon stored in permafrost
Summer= meltwater pools Carbon stored in biomass is low- low temp
Human Water taken from rivers reduces run off Building of extraction plants= release CO2
Management:Builidings and pipelines elevated to allow cool air to circulate, protecting permafrost. Refrigerated supports used to stabalise permafrost temperature.
