    • Weathering is the process of breaking down rocks, soils, and minerals through contact with the Earth's atmosphere, waters, and biological organisms.
    • what are the 3 atmospheric circulation cells?
      Hadley ,polar, ferrel
    • what are trade winds?
      surface winds that blow towards the equator
    • what are westerlies?

      surface winds that blow towards the pole
    • what are deep ocean currents caused
      differences in water density
    • what are surface currents caused by?
      by wind
    • what does a low pressure belt cause?
      High rainfall
    • what does a high pressure belt cause?
      low rainfall
    • what are glacial periods?
      Ice ages
    • what are interglacial periods?
      warm periods
    • what is the greenhouse effect?
      greeenhouse gases absorb heat that has been reflected off the earth and radiates heat back to earth
    • what are natural causes of climate change?

      aesteroid collisions,solar output variation,volcanic activity,orbital changes
    • name all fossil fuels
      coal petrol natural gas and oil
    • how can farming create greenhouse gases
      rice paddies produce methane which is a greenhouse gas
    • how does transport create greenhouse gases?
      most cars run on fossil fuels which create greenhouse gases
    • how does energy cause greenhouse gases
      when fossil fuels are burned carbon dioxide is produced
    • evidence that human activity is causing climate change
      Warming oceans, declining arctic ice,global temperature rise,sea level rise,more extreme weather events
    • Physical Hazards of Tropical Cyclones
      High winds,Storm surges,Intense rainfall
    • impacts of tropical cyclones on people
      • damaged transport can stop aid from arriving
      • food shortages
    • impacts of tropical cyclones on environment
      • strong winds can destroy trees
    • Vulnerability to Tropical Cyclones

      Geographic/physical vulnerability-Netherlands would be vulnerable because of their low-lying land
      Social vulnerability-Lower-income nations usually have lower quality housing
      Economic vulnerability-Less wealthy countries are more vulnerable because they will have less money to spend on flood defences
    • Which of these nations has low-lying land but isn't on a traditional cyclone path?
      The Netherlands
    • Reducing the Impacts of Tropical Cyclones
      1. Prediction and weather forecasting
      2. Protection
      3. Planning
