Siders77 Posted January 29, 2006 Report Share Posted January 29, 2006 Hey guys. I have an oral exam in Geography on Tuesday and I'm stuck on a question I have to answer. It's probably really easy to answer but my mind's gone blank. The question is: "How has the destruction of the rainforest contributed to the Greenhouse Effect?" I've searched Google but not had much luck. Cheers for any help. Quote Link to comment Share on other sites More sharing options...
Boothy Posted January 29, 2006 Report Share Posted January 29, 2006 The trees are burnt to provide enegy, which adds to it.Trees take in carbon dioxide, and release ooxygenThe trees that are flattened are often eplaced by industry or cities, which all add to pollution and the greenhouse effectThats all I can think of atm, not heard of oral exams in geography!

rich4130 Posted January 29, 2006 Report Share Posted January 29, 2006 Eaaaaasy.Less Trees to absorb the excess Carbon Dioxide produced from the burning of fossil fuels etc, casuing it to stop the short wave heat radiation returning back through the atmospheare, or something along those lines.

Ben Cox Posted January 29, 2006 Report Share Posted January 29, 2006 the destruction of the rainforest contributes because trees convert the carbon dioxide in the atmosphere into oxygen, you take away the trees and the co2 stays in the atmosphere with all the exhaust fumes and forms a blanket over the earth that lets the suns rays in but wont let them out again (like a greenhouse)Ben Quote Link to comment Share on other sites More sharing options...
matthewholdsworth Posted January 29, 2006 Report Share Posted January 29, 2006 use key words like...........deforestationMultinational corporations - money grabbin destroy rainforestsarea the size of wales.the answer is straight forward enough but if the exam is oral then u should try and get the key words in to make it sounds even better. examiners like to hear technical terms, helps make u sound better and will bring ur grade up. increasing world pop placing strain on rainforest, deforestation removes the "lungs of the earth" and reduces the capacity to cope with the excess co2just a thought but the question could be asking u to compare the effects of deforestation other causes of global warming, eg industrialisation and the growing autopolis nature of urbanisation. dont know how relavent this line of discussion would be Quote Link to comment Share on other sites More sharing options...

modx-lite Posted January 29, 2006 Report Share Posted January 29, 2006 Also I remeber something about the farming being pretty important - deforestation and intense farming meaning soils lose all their nutrients, making it impossible for trees to grow there again any time soon, i.e. problem escalates really quickly. Good luck Quote Link to comment Share on other sites More sharing options...
mikey23 Posted January 30, 2006 Report Share Posted January 30, 2006 also if they burn the trees that the have cleared = C02because when u burn wood, carbon dioxide is released Quote Link to comment Share on other sites More sharing options...

Good luck yep that would compound the problem, process known as desertification Quote Link to comment Share on other sites More sharing options...
