carbon cycle

• what are the two main causes that lead to an increase in carbon dioxide in the atmosphere


  combustion and deforestationSee an expert-written answer!We have an expert-written solution to this problem!
• what is meant by combustion and how does it effect the carbon dioxide levels in the atmosphere


  this is the burning of fossil fuels that releases carbon dioxide that was previously locked up
• what is meant by deforestation and how does it effect the carbon dioxide levels in the atmosphere


  this is when trees are being taken down , leading to less carbon dioxide being absorbed by photosynthesis
• What is the greenhouse effect?


  this is when green house gasses trap low energy ,longer radiation from earth that are re-radiated back towards the earths surface
• what is the primary effect caused by the greenhouse effect


  the constant rising of earths temperature
• what is a advantage of the green house effect


  it enables the temperature of earth to be high enough to sustain life
• list examples of greenhouse gasses


  carbon dioxide , methane , nitrous oxides and water vapour
• what are the consequences of the greenhouse effect


  raises the temperature , melting of polar ice caps , climate change , increased frequency of forest fires , decrease in ph of oceans
• why is agriculture particularly vulnerable to climate change


  this is because climate change causes changes in temperature and timing and quantity of rain
• what greenhouse gasses are produced from farm animals naturally


  methane
• what is meant by a carbon footprint


  The amount of carbon dioxide emitted into the atmosphere due to the actions of an individual or product
• how can we reduce our carbon footprint


  drive less , use less air-conditioning and heating , avoid waste food and plant trees
