Deforestation reduces rainfall in an area. The BEST explanation is:
ATrees absorb rainwater directly from clouds
BTrees release moisture into the air through transpiration; with fewer trees, the air becomes drier, fewer clouds form, and rainfall drops
CTrees reflect away sunlight that would heat the ground
DTrees burn up the clouds
Answer & Solution
Correct answer: B. Trees release moisture into the air through transpiration; with fewer trees, the air becomes drier, fewer clouds form, and rainfall drops
Forests participate in the water cycle: their leaves transpire huge volumes of water vapour into the atmosphere. This moisture feeds cloud formation and contributes to rainfall — locally and downwind. Cutting forests reduces this vapour flow, dries the atmosphere, and weakens the rainfall pattern. Combined with the warming caused by released CO₂, deforestation can shift entire regional climates.
