Presentation Transcript

  1. Chapter 22

  2. 1. Layers of Atmosphere • Exosphere- least pressure • Thermosphere-hottest, least pressure • Mesosphere-coolest, meteors • Stratosphere-ozone • Troposphere- weather, most pressure

  3. 2. Earth Sun Relationships Summer Solstice Sun Winter Solstice Sun

  4. 3. Seasonal Dates • Summer Solstice- June 20th-22nd • Winter Solstice- December 20th-22nd • Autumnal Equinox- September 20th-22nd • Vernal Equinox- March 20th – 22nd

  5. 4. 24 hrs of daylight in North Pole? • Summer Solstice

  6. 5. Nitrogen Cycle Steps • C • B • A • D

  7. 6. Photosynthesis • Puts Oxygen back into the air which is needed for life

  8. 7. Transfer of Energy • A. Lost • B. Gained • C. Lost

  9. 8. Impact of CFC’s • Chlorofluorocarbons • Destroys Ozone

  10. 9. Convection, Conduction, Radiation • A. Convection- Transfer of energy through hot rising and cool sinking in circular motion moving heat throughout. Popcorn air popper. • B. Conduction- Transfer of energy through direct contact. Popcorn cooking on stove • C. Radiation- Transfer of energy though waves most of which are invisible. Microwave popcorn

  11. 10. Greenhouse Effect • Traps solar radiation that is not absorbed at first by Earth. Keeps us warm.

  12. 11. Global Warming • Atmosphere gets too hot and CO2 increases.

  13. Chapter 23

  14. 1. Things that form clouds • 1. Unstable air • 2. Air lifting mechanism • 3. Condensation nuclei “dirty air” • 4. Saturated air

  15. 2. Air Lifting Mechanisms • Orographic Lifting • Convergence • Frontal Wedging • Convection

  16. 3. Cloud Classification • Shape • Height

  17. 4. Basic Cloud Types • Cirrus- Thin, wispy, and white • Cumulus- Fluffy, white, and big • Stratus- Shapeless, gray, thick, and covering

  18. 5. Clouds a weather • High cumulus and cirrus clouds indicate clear weather • Low cumulus (cumulonimbus/cumulus) Stratus (nimbostratus) indicate precipitation

  19. 6. Cloud Height • High (above 6,000 m)- cirrus, cirrostratus, cirrocumulus Cirr- Middle (btw, 2,000-6,000) - altocumulus and altostratus Alto- Low- (below 2,000 m) stratus, stratocumulus, and nimbostratus Strat-

  20. 7. and 8. Air temp and moisture • Hot air holds more moisture than cool air. • Increase in air temp means increase in moisture • T or F: True

  21. 9. When is air saturated • 100%

  22. 11. Content vs. capacity • The air cannot hold more than it is capable of

  23. 12. Humidity Problems • 1. 8; -17 • 2. 81;15 • 3. 51;10 • 4. 9; -10 • 5. 7; 48 • 6. 35; 57% • 7. 5; 100% • 8. 47; 85% • 9. 10; 50% • 10. 20; 75%
