    2. 2. Weather • Over a short period of time
    3. 3. Climate • Occur over a long period of time
    4. 4. Climate Zones • The earth in divided into 6 climate zones • 2 Torrid Zones (warm all year) • 2 Temperate Zones (cooler and has seasons) • 2 Frigid Zones (cool to subzero all year)
    5. 5. Frigid Frigi d Torrid Torrid
    6. 6. Factors that affect climate 1. The sun – The sun strikes the earth unevenly and certain parts of the earth receive more heat than others
    7. 7. 2. Latitude – How far an area is from the equator
    8. 8. 3. Elevation – Height above sea level – The higher you climb, the colder it gets
    9. 9. 4. Large bodies of water – Precipitation and ocean currents affect climate
    10. 10. 5. Mountain ranges
    11. 11. CLIMATES • Wladimir Köppen developed classification system for climates
    12. 12. Tropical Climates • Have high temperatures and heavy precipitation
    13. 13. 2. Savanna
    14. 14. Dry Climate
    15. 15. 1. Desert
    16. 16. • Desert – less than 10” of precipitation a year and big difference in nighttime and daytime temperatures
    17. 17. 2. Steppe
    18. 18. Steppe – average 10-30” of rain a year
    19. 19. Mild Climates
    20. 20. Humid subtropical – mild winters and hot, moist summers
    21. 21. 2. Marine West Coast
    22. 22. Marine West Coast – dry winter with regular rainfall
    23. 23. 3. Mediterranean
    24. 24. Mediterranean – found surrounding the Mediterranean Sea
    25. 25. Continental climates • Seasonal extremes in temperature and precipitation
    26. 26. 1. Humid Continental
    27. 27. Humid Continental – cold winters and warm to hot summers
    28. 28. 2. Subpolar
    29. 29. Subpolar Climates – snow climates
    30. 30. Polar Climates
    31. 31. 1. Polar Ice Cap
    32. 32. Polar icecap – permanent ice and snow
    33. 33. 2. Tundra
    34. 34. Tundra – has snow, but has a short season when temperatures may rise above freezing
    35. 35. Highland Climates • Resemble polar climates
    36. 36. Renewable vs nonrenewable resources
    37. 37. Renewable Resources • Water • Soil • Air • Trees • Waterpower • Geothermal energy (heat from the Earth’s interior) • Wind • Solar energy (energy from the sun)
    38. 38. Nonrenewable Resources • Exist in limited quantities and cannot be replaced – Iron – Bauxite (make aluminum) – Fossil fuels (coal and petroleum) – Nuclear energy (uranium)
