1. How is wind connected to all life on earth?

2. Why is one area of the earth’s land surface a desert, and other a grassland, and another a forest? Why do different types of deserts, grasslands and forest exist?

3. Climate and Weather Chapter 6, first part

4. Key Concepts  Factors influencing weather and climate  Effect of climate on distribution of biomes  Characteristics of major biome types  Saltwater and freshwater life zones  Human impacts on biosphere

5. Weather and Climate  What is weather?  How meteorologists predict weather  What is climate? temp, humidity, precipitation, sunshine, cloud cover, wind dir. Radar, satellites, aircraft, stationary sensors, feed into computers General pattern of atmospheric conditions over a long period

6. Factors Associated with Climate  Temperature  Precipitation  Uneven heating  Seasons  Earth’s rotation  Properties of air and water Fig. 6-2 p. 107

7. Polar (ice) Subarctic (snow) Cool temperate Warm temperate Dry Tropical Highland Major upwelling zones Warm ocean current Cold ocean current River Fig. 6-3, p. 108 Global Climatic Zones

8. Seasons Fig. 6-4 p. 108

9. Latitude The curvature of the earth’s surface affect the amount of Solar Insolation an area receives

13. 1.Water has high specific heat - It can absorb or give of a lot of heat without changing temperature 2.Areas close to large bodies of water have moderated temperature regimes cooler in summer warmer in winter 3.Increase precipitation for proximal lands What effects do large bodies of water have on climate?

21. Greenhouse Effect  Greenhouse Effect  Greenhouse gases  Human impact  Global warming  Impacts of global warming

22. Greenhouse Gasses Gasses that determine earth’s average temperatures Include: –Water vapor (primary greenhouse gas) –Carbon dioxide –Methane –Nitrous oxide –Synthetic chlorofluorocarbons (CFCs, aerosol cans) –Synthetic perfluorocarbons (refrigerating units) –Synthetic trifluoromethyl sulfur pentafluoride (high voltage equipment)

23. Ozone Layer  Located in stratosphere  UV protection  Decline in ozone  Consequences of ozone decline

28. Microclimates Fig. 6-10, p. 112  Rain shadow effect a Winds carry moisture inland from Pacific Ocean b Clouds, rain on windward side of mountain range c Rain shadow on leeward side of mountain range Moist habitats Dry habitats  Cities  Land-ocean interactions

29. Biomes  Climatic effects on biomes  Not uniform  “Mosaic of patches”  Effects of latitude and altitude

30. Dry woodlands and shrublands (chaparral) Temperate grassland Temperate deciduous forest Boreal forest (taiga), evergreen coniferous forest (e.g., montane coniferous forest) Arctic tundra (polar grasslands) Tropical savanna, thorn forest Tropical scrub forest Tropical deciduous forest Tropical rain forest, tropical evergreen forest Desert Ice Mountains (complex zonation) Semidesert, arid grassland Tropic of Capricorn Equator Tropic of Cancer Fig. 6-11, p. 113 Earth’s Major Biomes

33. Climatograms http://www.geocities.com/Athens/Parthenon/1020/images/des_grass.gif Rainfall = bars Temperature = line So all graphs have the same scale: Rainfall (Left Y axis) 3 squares = 4 cm rainfall Temperature (R Y axis) 3 squares = 8 degrees temp. X axis Each month = 2 squares
