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.
