13. List the layers of the atmosphere starting at Earth’s surface. Include the
exosphere. . . . . . . . troposphere , stratosphere, mesosphere, thermosphere
(ionosphere), exosphere.
14. TRUE / FALSE. The sun is found in the exosphere layer. .. . . . false
15. Which element makes up 78% of our air? . . . . nitrogen
16. Which element makes up 21% of our air? . . . . . oxygen
17. In which layer is most of our air found? . . . . . troposphere
18. What is the chemical formula for ozone? . . . . . . O3
19. Why is the ozone layer important to us? . . . . protects us from harmful
ultraviolet rays from the sun.
20. What are two natural sources of air pollution? (not man- made) . . . . forest fires
and volcanic eruptions
21. What are two sources of pollution that are caused by humans? . . . . . burning
fossil fuels and exhaust from trucks and cars
22. As you move through the troposphere to the stratosphere, the
temperature . . . . decreases
.
23. As you move through the stratosphere to the mesosphere, the
temperature . . . . increases .
24. As you move through the mesosphere to the thermosphere, the
temperature .. . . . decreases
25. What is air pressure? . . . . . . the force exerted on a surface by the air above it
26. Is air pressure greater in the stratosphere or the exosphere? . . . . stratosphere
27. Why is air pressure greater at sea level than at the top of the mountain? . . . .
there is more air above you, pressing down on you at sea level
28. Why would you need to wear an oxygen mask when climbing a really high
mountain? . . . . . . . the air is less dense so there is less air to breathe
29. Which is most dense - - the air in the stratosphere or in the troposphere? . . . .
troposphere
30. Which is most dense - - the air in the troposphere or in the thermosphere? . . . .
troposphere
31. What force holds the atmosphere close to Earth? (If we didn’t have this, our
atmosphere would be lost in space!) . . . . gravity
32. What weather instrument measures air pressure? . . . . barometer
