Climate Part 2 Presentation Transcript

  • 1. Climate Part Deux
  • 2. Ocean Currents
    • Currents are moving streams of water in the earth’s oceans.
    • *Ocean currents are continuously moving in a similar way as winds. Can you guess how they move?
  • 3. Ocean Currents
    • * Warm currents move along the equator or from the equator to the poles.
    • * Cold currents carry cold polar water towards the equator.
  • 4.  
  • 5.  
  • 6. Local Winds
    • Patterns of wind caused by landforms in a particular area
  • 7. Sea and Land Breezes
    • Land warms and cools quicker than water
      • Land = Water =
  • 8.  
  • 9.  
  • 10. Mountains
  • 11. Coastal Mountains
    • Windward side - moist and often foggy with thick, green vegetation
    • Leeward side - dry area facing away from the wind
      • Rain Shadow
  • 12. Ex. Sierra Nevada and The Great Basin
  • 13. The Impact of People on Climate
    • Cities are warmer than in rural areas
    • Why?
  • 14. The Impact of People on Climate
    • City streets and buildings absorb more of the sun’s rays than do the plants and trees of rural areas.
    • People burn fossil fuels for heat, to power industry and move cars
  • 15. The Greenhouse Effect
    • Buildup of certain gases in the atmosphere that, like a greenhouse, hold more of the sun’s warmth
  • 16.  
  • 17. Impact of People - Rain forests
    • Rain forests - dense forests near the equator that receive high amounts of rain
  • 18. Impact of People - Rain forests
    • Some people want to clear the forests to sell the lumber or use the land for farming
  • 19.  
  • 20. What is a result of deforestation?
  • 21. Impact of People - Deforestation
    • Burning of trees releases harmful gases
    • If trees are cut, less water will evaporate (transpiration), which means less rainfall.
  • 22. That’s it for Section 2!
