Can someone help with a geography A level question?Watch this thread
"Assess the potential causes and impacts of changes to the water balance within a tropical rainforest that you have studied"
Its a 20 mark question and I am doing AQA so we learnt about the Amazon rainforest.
Use your notes as fodder for your essay
Pay attention to the number of marks
Find out about the Amazon rainforest online (if you use Wikipedia then make sure to quote instead).
The answer from @tinygirl96 is highly unhelpful. I do OCR Geography A-Level (2nd Year) but I think they are similar. I would firstly start off with an introduction about how humans are affecting the water imbalance in the Amazon - for example deforestation and agriculture, they are the two main ones I would think the question is referring to. Then I would do maybe 3 or 4 main paragraphs talking about human affects on water imbalance in the Amazon, with some facts and figures - for example transpiration and evapotranspiration rates would be reduced if trees were removed from the rainforest, hence this would increase the surface storage of water - so higher surface run off rates and increase risk of flooding. Also, root uptake would be reduced; similar consequences. Agriculture uses crop irrigation techniques, I am pretty sure they divert some of the Amazon River, which will decrease the river discharge and fluvial storage of water. Agriculture usually initially begins with the removal of trees - so Link back to what has previously been said. Then you could also say about since there will be less water in the atmosphere, there will be more intense sunlight, possibly killing some of the plants - which is a positive feedback loop. Then finish with a conclusion - weighing up if deforestation or farming has the most impact on the water cycle.
I have attached a similar essay that I have done, I know it isn't exactly the same but it will give some ideas.
