Effects Of Deforestation

Question 1

Flooding risk

Answer 1

Less interception = to much water for soil to soak up = SR = flood risk

Question 2

Drought risk (5)

Answer 2

Reduced rate of evapotranspiration = less water vapour = less clouds = less rainfall = drought

Question 3

Impact on soil (3)

Answer 3

No roots to hold soil = leaching + soil erosion = carbon transferred from soil to hydrosphere

Question 4

Impact on regrowth (4)

Answer 4

Less leaf litter = reduced humus = soil can’t support regrowth = limits carbon absorbed from photosynthesis

Question 5

Impact of climate change on Amazon (3+)

Answer 5

Temp increases and rainfall decreases = drought
Plants and animals in A adapted to moist conditions = extinct
Drought = wildfires = combustion = co2 and further deforestation

Question 6

What do scientist say of temp increase (2)

Answer 6

4% temp increase = kill 85% of Amazon
Carbon sink
