3.2 - Climate

  1. 1. Climate
  2. 2. <ul><li>Wind Currents </li></ul><ul><li>Wind is caused through convection </li></ul><ul><ul><li>Sun heats the air - the heated air expands and creates low-pressure area – cooler air rushes into low pressure area </li></ul></ul><ul><li>Hot air goes towards the poles and cold air towards the equator </li></ul><ul><li>Coriolis effect causes winds to bend </li></ul>
  3. 3. <ul><li>Ocean currents </li></ul><ul><li>Flow throughout the ocean </li></ul><ul><li>Help regulate temperatures and precipitation </li></ul><ul><li>Zones of Latitude </li></ul><ul><li>Tropical is from equator to the tropics of Cancer and Capricorn and are hot all year </li></ul><ul><li>Temperate is from the tropics to the polar regions and vary in temperature </li></ul><ul><li>Polar is around the poles and is cold all year </li></ul>
  4. 6. <ul><li>Elevation </li></ul><ul><li>The higher you get, the colder it is </li></ul>Mt. Kilimanjaro. It’s glacier top cap that has been there for nearly 11,000 years is almost completely gone now due to warming.
  5. 7. <ul><li>El Nino and La Nina </li></ul><ul><li>Winds blow east over the Pacific Ocean in El Nino and pushes warm water towards American west coast. Causes more rain there and drought in Asia and Australia. </li></ul><ul><li>In La Nina, the reverse occurs. </li></ul>
  6. 9. <ul><li>Global Warming </li></ul><ul><li>Greenhouse effect causes global temperatures to rise </li></ul><ul><li>Solar energy hits earth and heat reflects back into space. Except that gases like carbon dioxide trap the heat </li></ul><ul><li>Debated how accurate and how severe the phenomenon is </li></ul>
