Chapter 22

1. Layers of Atmosphere

• Exosphere- least pressure

• Thermosphere-hottest, least pressure

• Mesosphere-coolest, meteors

• Stratosphere-ozone

• Troposphere- weather, most pressure

2. Earth Sun Relationships

Summer Solstice Sun

Winter Solstice

Sun

3. Seasonal Dates

• Summer Solstice- June 20th-22nd

• Winter Solstice- December 20th-22nd

• Autumnal Equinox- September 20th-22nd

• Vernal Equinox- March 20th – 22nd

4. 24 hrs of daylight in North Pole?

• Summer Solstice

5. Nitrogen Cycle Steps

• C

• B

• A

• D

6. Photosynthesis

• Puts Oxygen back into the air which is needed for life

7. Transfer of Energy

• A. Lost

• B. Gained

• C. Lost

8. Impact of CFC’s

• Chlorofluorocarbons

• Destroys Ozone

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

10. Greenhouse Effect

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

11. Global Warming

• Atmosphere gets too hot and CO2

increases.

Chapter 23

1. Things that form clouds

• 1. Unstable air

• 2. Air lifting mechanism

• 3. Condensation nuclei “dirty air”

• 4. Saturated air

2. Air Lifting Mechanisms

• Orographic Lifting

• Convergence

• Frontal Wedging

• Convection

3. Cloud Classification

• Shape

• Height

4. Basic Cloud Types

• Cirrus- Thin, wispy, and white

• Cumulus- Fluffy, white, and big

• Stratus- Shapeless, gray, thick, and covering

5. Clouds a weather

• High cumulus and cirrus clouds indicate clear weather

• Low cumulus (cumulonimbus/cumulus) Stratus (nimbostratus) indicate precipitation

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-

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

9. When is air saturated

• 100%

11. Content vs. capacity

• The air cannot hold more than it is capable of

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%
