Atmosphere study guide

TermDefinition
1. List the examples of local winds. Sea and land breeze,Mountain and valley breeze
2. What are "auroras" and where are they found? They are lights in the thermoshere, it is found in northern regions. (ionosphere)
3. Our Ozone layer absorbs which type of harmful radiation from the sun? UV light
4. How much oxygen and carbon dioxide is found in the air? 1% carbon, 21% Oxygen.
5. Which global wind blows away from the poles to the west. Polar easterlies
6. What are the 2 most abundant gases found in the air? nitrogen and Oxygen
7. Describe air pressure. It is the amount of air above you, it measures the weight.
8. What happens to air pressure as altitude increases? It decreases.
9. Describe "Jet streams". It is like a conveyor belt, it is faster moving air in the troposphere.
10. What is green house effect? It is energy that enters the atmosphere and bounces of the ground and due to the gases in the atmosphere it comes back to earth again.
11. Explain the 3 ways of heat transfer. There is radiation, conduction, and convection.
12. Where do trade winds flow toward? They flow to the equator.
13. What does the "Coriolis Effect" make the winds do? It makes them turn to the west.
14. Describe the doldrums. Slow moving air at the equator.
15. What is the Ozone layer? The Ozone layer is gases in the air that protect us from the the sun`s energy.
15. Where is the Ozone layer? Stratosphere
16. Describe the "Thermoshere". It is the layer closest to space.
17. What is the most common atmospheric gas? Nitrogen
18. What parts of the earth cools off faster and heats up faster? What does this unequal heating create? It is land. It creates land and sea breeze also it is mountain and valley breeze.
19. What is smog? It is smoke and fog combined.
20. Describe the movement of convection currents. Energy transfer by circulation
21. Which instrument measures air pressure? barometer
22. What is significant about the troposphere? We live in the troposphere. Weather is in this layer.
23. What kind of ways have humans created air pollution? industrial emittiions, car exhast, and valcanic ash.
24. What is another name for the distance above sea level? The air above is called altitude or elevation.
25. What are global winds? They are mass amounts of air in the sky. There is 3 global winds.
26. What does the name of a wind tell you? Where it starts from.
27. How much of the sun’s energy actually reaches the Earth? 2 billionths
28. What property are the layers of the atmosphere based on? Temperature
29. Which calm area is located around 30 degrees north and south latitude? Horse latitude.
30. What is the atmosphere? it is the layer of gases surrounding the earth.
31. List the 3 global winds and the 2 calm areas. polar easterlies, westerlies, and trade winds. Doldrums and Horse latitude.
32. What is global warming? It is the heat from green house effect and it melts the ice at the poles.
33. If air mass increases what happens to density? It increases.
34. What type of winds blow over short distances? Local winds
35. How are all winds created? It is the pressure differences. Or unequal heating of the earth.
