  1. Weather and Climate Glenco Chapter 17 Pearson Chapter 24

  2. Earth’s Atmosphere • The air is a mixture of gases, Nitrogen, Oxygen and trace gases. • Microorganisms produce the gases. • The theory is that over time the atmosphere developed into the air we now breath.

  4. Atmospheric structure • Weather takes place in the Troposphere. • Ozone is in the Stratosphere. As altitude increases, Air pressure and density Decrease.

  5. Latitudes and Longitudes

  6. Latitude and Longitude • These affect the climate based on the angle of the Sun’s rays.

  7. Heating (energy in) the Atmosphere

  8. Wind • Winds are caused by differences in air pressure • Local Winds: are caused by unequal heating of the earth’s surface in a small area.

  9. Global Winds • Winds that blow over long distances from a specific direction. • Move in huge bands called convection cells • Warm air at the equator rises and replaced by cooler air. • Called, Trade winds,Westerlies, and polar easterlies

  11. Water in the Atmosphere

  12. Humidity • The amount of water vapor in the air • This can condenses as dew, frost or fog if the air temperature drops.

  14. Classifying clouds

  15. Using your book add details to the types of clouds. Pg 762-763

  16. Weather Patterns • Pg 765- 771 in Pearson book • Answer 24.5 assessment questions 1-6 pg 771

  17. Climates • Two things determine a regions climate: • Temperature and Precipitation

  18. Temperature • Latitude • Distance from large bodies of water • Ocean currents • altitude

  19. Precipitation • Latitude • Distribution of air pressure systems • Global winds • Mountain barriers http://mycozynook.com/102RGCh34OH.htm

  20. El Nino • Warming of water in central and eastern Pacific Ocean • A current of water moves west • Causes a different weather pattern

  21. Global Warming now called Climate Change • One possible theory is the increase of Co2 and other gases in the atmosphere is causing climate change. • The green house effect.

  22. Possible cures • Energy Conservation • Alternative non carbon producing power sources: Please list them for yourselves. • Reduce the amount of gases produced.

  23. Research • Using your laptops please research and write a one paragraph summation of current US policy addressing Climate Change. • Google: “current US policy on climate change” • EPA.gov/ climate change
