Fragile Environments and Climate Change - Coggle Diagram

- - - - distribute heat around the earth, and a change in currents lead to periods of warming and cooling around the pacific
    - - large eruptions emit ash and sulfur dioxide, preventing the sun from reaching the Earth's surface and reflects it back into space. this cools the earth and lowers global temperatures
    - - energy from the sun isn't constant, and works in cycles. Black areas on the sun are called sunspots, and when these are dark in colour show the suns activity, with more spots meaning more solar energy, so therefore higher temps
  - - - use of oil, coal and gas increase as population grows, burning fuels for industry, transport and energy lead to an increase in CO2. these cause and enhanced greenhouse effect, which traps heating, causing increased temperatures
    - - as population increases, more land is used for agriculture and housing, which involves rainforest burning and cleaning, emitting large amounts of CO2, with less trees to remove CO2, causing excess CO2 to be released back into the atmosphere, raising global temps.
    - - land needed for crop production increases due to population growth, with an increase in methane from rice fields, landfills and animals. this contributes to the greenhouse effect, raising global temperatures
- - - - very wet with over 2000mm of rainfall per year
      - very warm with an average daily temperature of 28 C and never drops below 20 C
      - hot and humid
    - - not very fertile
      - t
