Assess the potential causes and impacts of changes to the water
balance within a tropical rainforest that you have studied.
The exam board I have is AQA so we learnt about the Amazon rainforest. Can someone help?

so explain the effects of changing the water cycle and the carbon cycle in the tropical rain. forest.(they are both interlinked) So when deforestation occurs there is less interception and an increase in surface run off so that causes more flooding because theres higher levels of water in the rivers. As deforestation occurs there is more carbon and methane released into the atmosphere increasing the temperature and increasing evaporation which means more rivers dry out quicker.
I'm not sure if you do this in AQA but have an introduction to give all your facts and statistics. And a conclusion maybe too.
hope this helps.
When writing always ask yourself so what?/why?
There is less water in the rainforest due to climate change and deforestation. why? This is due to the increase in temperature as a result of human activity in the rainforest etc.
