The document provides an overview of key concepts to learn about the atmosphere including its layers, composition, air pressure, weather factors like heat transfer and winds, clouds, and electromagnetic radiation from the sun. It includes review questions testing understanding of these concepts like what absorbs ultraviolet radiation, the greenhouse effect, types of heat transfer, what causes wind, tools to measure variables, and more.

1. Look at your Atmosphere KWL chart. Now that we have studied the atmosphere, fill in the L on the chart (what you have learned). Turn in your lab from yesterday if you did not turn it in yesterday.

Atmosphere ( page 134 & 118-125) Layers Composition (%’s of O2 & N2) Air Pressure & how it affects our bodies Weather Factors (page 135 & 126-137) Heat Transfer (radiation/convection/conduction) Electromagnetic radiation from the sun (IR, visible, UV) Winds – local (land & sea) and global Clouds – types (cumulus, cirrus, stratus, cumulonimbus)

4. What absorbs ultraviolet radiation in the atmosphere? Ozone

5. What type of energy heats up the Earth’s atmosphere? Infrared radiation

6. What is the greenhouse effect? Process by which gases hold heat in the atmosphere

7. What type of heat transfer requires two objects to be touching? Conduction

8. How is heat transferred to you from a campfire? Radiation

9. What type of heat transfer is responsible for heating the troposphere? Convection

10. Why does convection happen? Warm air is more dense than light air Warm and cold air have the same density Cold air is less dense than warm air Cold air is more dense than warm air

11. Wind is caused by differences in Precipitation Humidity Air pressure Turbulence

12. What tool do we use to measure wind speed? Anemometer

13. How are local winds different from global winds? Local winds are caused by unequal heating in a small area

14. Why do land breezes form? Because land cools off faster than water

15. What type of wind blows from a specific direction over long distances? Global wind

16. Earth’s rotation makes winds seem to curve. What is this called? Coriolis effect

17. What tool is used to measure relative humidity? Psychrometer

18. When do clouds form? When water vapor condenses

20. What are high feathery clouds called? Cirrus

21. What type of clouds are layered and cover most of the sky? Stratus

22. Any form of water that falls from a cloud is called what? Precipitation

23. How does energy travel through space to the Earth? As electromagnetic waves

24. Energy from the sun that reaches the Earth is visible light, infrared radiation and _______________. Ultraviolet radiation

25. What tool is used to measure how hot or cold the air is? Thermometer

26. A sea breeze is a type of what kind of wind? Local wind

27. What tool is used to measure air pressure? Barometer

28. Which heats up more quickly, land or water? Land

29. What is the most abundant gas in the atmosphere? Nitrogen

30. What percent of the atmosphere is oxygen? 21%

31. What is altitude? The measurement of how high something is above sea level

32. What human activity causes the most air pollution? Vehicle exhaust

33. What is rain or sleet mixed with acids called? Acid rain

34. Why does air have pressure? Because it has mass

35. How do we measure air pressure? With a barometer

36. What does the ozone layer do? Protects us from ultraviolet radiation

37. Photochemical smog forms in the presence of what? Sunlight

38. What happens to happens to air pressure as altitude increases? It decreases

39. In what layer of the atmosphere is the ozone layer or ozonosphere found? Stratosphere

40. What are the four main layers of the atmosphere in order from the ground upwards? Troposphere, stratosphere, mesosphere, thermosphere

41. What does the mesosphere do? Causes meteors to burn up before striking Earth

42. Where does the aurora borealis form? In the ionosphere

43. Where does weather occur? The troposphere
