Effects Of Deforestation Flashcards
Flooding risk
Less interception = to much water for soil to soak up = SR = flood risk
Drought risk (5)
Reduced rate of evapotranspiration = less water vapour = less clouds = less rainfall = drought
Impact on soil (3)
No roots to hold soil = leaching + soil erosion = carbon transferred from soil to hydrosphere
Impact on regrowth (4)
Less leaf litter = reduced humus = soil canβt support regrowth = limits carbon absorbed from photosynthesis
Impact of climate change on Amazon (3+)
Temp increases and rainfall decreases = drought
Plants and animals in A adapted to moist conditions = extinct
Drought = wildfires = combustion = co2 and further deforestation
What do scientist say of temp increase (2)
4% temp increase = kill 85% of Amazon
Carbon sink
Droughts in Amazon specific example (3)
