3. Final Exam
Exam will be in four parts, 20 questions each (80 total, all multiple choice)
Part 1: The Atmosphere
Part 2: Weather Factors
Part 3: Weather Patterns
Part 4: Stars & Galaxies
Questions will be similar to, but not the same, as your quizzes
Each part counts as a quiz retake, but will not lower your grade

4. The Atmosphere Study all assignments & notes
Composition of the atmosphere
What is the most abundant gas in out atmosphere? What is the 2nd most abundant gas?
Know other important trace gases in our atmosphere (CO2, O3, H2O)
Know about particles in atmosphere, why are they important (2 main reasons)
How does the atmosphere allow for life on planet Earth?

5. The Atmosphere Know the three major properties of air
Mass, density, pressure
What is air pressure?
How is air pressure measured in weather reports? (inches of mercury, in Hg)
How is air pressure measured on weather maps? (millibars, 1000 bars, mb)
What type of instrument measures air pressure?
What does altitude mean?
What happens to air density with increased altitude?
What happens to air pressure with increased altitude?

6. The Atmosphere
Know the four major layers of the atmosphere, and what order they are in
What makes each layer different (temperature, density, pressure)
Troposphere (where we live)
Turbulent, chaotic, always changing layer. Where does most weather occur?
Which layer is lowest in altitude? Which layer has the highest air density and air pressure?
Stratosphere
Calm layer with little weather
Do we travel in the stratosphere? (jet planes, weather balloons)
Ozone Layer absorbs ultraviolet radiation (UV)

7. The Atmosphere Mesosphere Thermosphere
Most meteors and falling satellites burn up in this layer from heat caused by air friction
Thermosphere
Layer with highest altitude
Ionosphere: lower part, charged gas particles interact with charged solar particles to form auroras
Exosphere: higher part, blends into space gradually, no clearly defined boundary

8. The Atmosphere
What are pollutants? (harmful gases or particles in the air, water, or soil)
What are two major sources of pollution? (nature and human activities)
What is smog?
What is acid rain?

9. Weather Factors Know the three type of heat (energy) transfer
Where does our atmosphere get its energy from to drive the weather?
What type of heat transfer gets energy from the Sun to Earth’s atmosphere?
How does it travel through space?
Know about electromagnetic waves and the electromagnetic spectrum
What types of energy are part of the EM spectrum?
What is visible radiation?
What two types of non-visible radiation affect us every day?

10. Weather Factors
What happens to the Sun’s energy as it enters Earth’s atmosphere?
Some is reflected back into space
Some is absorbed by the atmosphere
Some is absorbed by Earth’s surface, and then radiated back into atmosphere at night
What is the greenhouse effect?

11. Weather Factors
What is wind? How does differences in air pressure affect the wind?
What instrument do we use to measure the wind?
What is the wind chill factor?
Explain local winds using the examples of land breezes and sea/lake breezes

12. Weather Factors
Understand the global convection currents that affect global winds
Calm areas: doldrums, horse latitudes
Wind belts: trades, westerlies, easterlies
Understand the Coriolis Effect
What is the jet stream?

13. Weather Factors
Understand the water cycle. How does water move between the atmosphere and Earth’s surface?
What is evaporation? What is condensation?
What is humidity? What is relative humidity?
What instrument do we use to measure humidity?
How do clouds form? (involves cooling and particles)
What is the dew point?

14. Weather Factors How do we classify clouds?
Shape: cirrus, cumulus, stratus
Altitude: low, middle, high
Fog
What is precipitation? Name major types of precipitation.

15. Weather Patterns Know the five major types of air masses
Maritime tropical
Maritime polar
Continental tropical
Continental polar
Continental arctic
Why do most air masses in the US move to the East, but hurricanes move to the West?

16. Weather Patterns Know what a front is, and the four major types
Cold front, warm front, stationary front, occluded front
What type of weather do cold fronts often bring?
What are highs (H) and lows (L) on weather maps? How do highs and lows relate to cyclones?
What is the difference between a cyclone and a cyclonic storm?

17. Weather Patterns
What is a thunderstorm? How is it different from other rain cloud systems?
What is a tornado? Where do tornados form? Understand tornado safety
Why do so many tornados form in Tornado Alley? (has to do with moving air masses)
What is a hurricane? Where do hurricanes form, and where do they move?
