16. What relationships are there between the water, carbon cycle and the environment in the TRF? Flashcards
How much CO2 is absorbed here?
Absorb huge amounts of CO2 and 28% of worldβs oxygen.
How do lots of leaves aid the water cycle?
Rainforests allow a considerable amount of water to be returned to the atmosphere through evapotranspiration.
How are floods mitigated by the water cycle in rainforestes
The canopy intercepts up to 75% of the rainfall, the other 25% is evaporated. Of this 75%, half is used by the plants and the other half either infiltrates into the ground or runs-off to the river.
why is warm and wet climate so good for rainforests?
Warm and wet climate ideal for plant growth, promoting photosynthesis and respiration.
Why is it such a big carbon sink?
Wood is 50% carbon so a huge carbon store and sink.
Why is decomposition so active?
Decomposition is active due to climatic conditions - high temperatures and moisture availability.
