13. How are the four layers of the Earth's atmosphere divided?
|
13. By temperature differences
|
|
14. Where is the ozone layer and why is it important to Earth? (Short Answer)
|
14. It is in the stratosphere. It prevents much of the UV radiation from reaching the Earth's surface
|
|
15. What is the major source of oxygen for the Earth's atmosphere?
|
15. Plants
|
|
16. Which atmospheric layer is the densest?
|
16. Troposphere
|
|
17. What has been higher in the Northern Hemisphere in the 2000s than at any other time in the past 600 years?
|
17. Surface Temperatures
|
|
18. What layer is immediately above the troposphere?
|
18. Stratosphere
|
|
7. What is the uppermost atmospheric layer?
|
7. Thermosphere
|
|
8. What is the coldest layer of the atmosphere?
|
8. Mesosphere
|
|
9. How does wind generally move?
|
9. From the poles toward the equator
|
|
10. When radiation reaches the Earth's atmosphere what happens to 5% of it?
|
5% is reflected by the Earth's surface
|
|
11. What percent of radiation that reaches the Earth's atmosphere is absorbed by ozone, clouds, and air?
|
20%
|
|
12. Name the four layers of the Earth's atmosphere in order of increasing altitude. (Lowest to Highest}
|
Troposphere, Stratosphere, Mesosphere, Thermosphere
|
|
1. What is the bottom layer of the atmosphere?
|
1. Troposphere
|
|
2. Which layer is ninety percent of the Earth's mass found in?
|
2. Troposphere
|
|
3. What does warm air in a cyclone do?
|
3. It rises and cools
|
|
4. What direction does air in a cyclone spin in the Northern Hemisphere?
|
4. Counterclockwise
|
|
5. When a hot sidewalk heats your feet by direct contact, what type of transfer of energy is it?
|
5. Conduction
|
|
6. Define atmosphere.
|
6. A mixture of gases that surrounds the Earth
|
|
31. What is the ozone layer?
|
31. The layer of the stratosphere that absorbs solar energy in the form of ultraviolet radiation.
|
|
32. What layer is the upper part of the mesosphere and the lower part of the thermosphere?
|
Ionosphere
|
|
33. Define temperature.
|
It is the measure of the average energy of moving particles in a substance
|
|
34. What gas is called a greenhouse gas?
|
Carbon dioxide
|
|
35. What is the Coriolis effect?
|
The curving of moving objects by the Earth's rotation
|
|
36. What major layer of the atmosphere is the ozone layer located in?
|
Stratosphere
|
|
25. What layer protects Earth from meteoroids?
|
25. Mesosphere
|
|
26. The temperature is 20F and the wind speed is 17 knots. If the wind speed changes to 22 knots, how many degrees cooler will the air feel? (Short Answer)
|
5F cooler
|
|
27. If the wind speed is 20 mi/h and the temperature is 30F, how cold will the air seem?
|
27. 4F
|
|
28. Each layer of the atmosphere serves a purpose. Give the major purpose for each layer.(Short Answer)
|
28. Troposphere--has gases for breathing
Stratosphere-- has the oz0ne layer which absorbs UV radiation Mesosphere--protects Earth from meteoroids Thermosphere--has ionosphere which absorbs harmful solar energy |
|
29. How does the Coriolis effect affect the way wind moves? (Short Answer)
|
1. It causes the curving of the winds.
2. It is caused from winds moving from high pressure to low pressure areas. 3. It moves from the poles to the equator. |
|
30. How do the winds in a cyclone and an anticyclone affect the weather? (Short Answer)
|
Cyclone(Low pressure)--warm, rising air brings clouds and rain
Anticyclone(High pressure)--cool, sinking air brings dry, clear weather |
|
19. Are cyclones associated with stormy weather or fair weather?
|
19. Stormy weather
|
|
20. What does air do that makes wind occur?
|
Wind is caused by air moving from regions of higher to lower pressure
|
|
21. As altitude increases, air pressure _____________________. As altitude decreases, air pressure _______________.
|
Decreases, increases
|
|
22. The air is mostly made of what?
|
22. Nitrogen
|
|
23. What would an increase in the greenhouse effect cause?
|
global warming
|
|
24. As you move upward through the atmosphere, what happens to the temperature?
|
It varies--it can increase and decrease.
