  4. 6. Local Winds <ul><li>Patterns of wind caused by landforms in a particular area </li></ul>
  5. 7. Sea and Land Breezes <ul><li>Land warms and cools quicker than water </li></ul><ul><ul><li>Land = Water = </li></ul></ul>
  6. 10. Mountains
  7. 11. Coastal Mountains <ul><li>Windward side - moist and often foggy with thick, green vegetation </li></ul><ul><li>Leeward side - dry area facing away from the wind </li></ul><ul><ul><li>Rain Shadow </li></ul></ul>

  14. 20. What is a result of deforestation?
  15. 21. Impact of People - Deforestation <ul><li>Burning of trees releases harmful gases </li></ul><ul><li>If trees are cut, less water will evaporate (transpiration), which means less rainfall. </li></ul>
  16. 22. That’s it for Section 2!
