  1. Atmosphere and weather 6th

  2. What are the main elements that make up our atmosphere? • If there is not much carbon dioxide, then why do we have such a problem making more of it? • What is ozone?

  3. In your words, what is air pollution? • How do particles affect air quality? • Where do they come from • Can we protect our self from them? • what is smog? • Why is it bad? • What is temperature inversion? • What causes it? • Can you think of an area that might be affected by this?

  4. How does pollution make acid rain? • What are the main forms of acid rain? • Nitrogen and sulfur dioxides • Where do they come from? • What are the main affects of acid rain?

  5. Air pressure • What is air pressure? • How do we measure air pressure? • How does air pressure change in altitude? • Why does that happen? • How does water vapor affect air pressure?

  6. Layers of the atmosphere • Troposphere- where we live and clouds • Stratosphere- why is it special • ozone • Mesosphere- • Thermosphere- is really hot, but registers cold- why? • Ionosphere- aurora borealis • Exosphere- out and away

  7. Electromagnetic spectrum- describe all of the wavelengths of energy. • Is it true that dark objects are hotter than white objects? • Using convection, conduction, and radiation, draw a picture to show how all 3 respond to earth and the sun.

  8. What is wind? • Where does it come from? • Multiple answers • What is the coriolis effect? • What causes the doldrums near the equator? • Sun a factor? • How does heating a cooling make wind?

  9. Evaporation- what is it? • Change in state of matter • Water vapor causes humidity • Relative humidity- the amount of water vapor air can hold • Can Warm air hold more water vapor than cool air?

  10. What is condensation? • What is the dew point? • Dew point changes based on humidity and temperature. • Review precipitation.

  11. Fronts • Draw and describe each type • Cold front • Warm front • Occluded front • Stationary front • Describe how air move differently across land and water • Which gets more humid air?
