  1. Chapter 15 - Atmosphere

  2. Question 1 - 10 What are the two major gases in the atmosphere?

  3. Answer 1 – 10 Nitrogen & Oxygen

  4. Question 1 - 20 What happens to air pressure as altitude increases?

  5. Answer 1 – 20 It decreases.

  6. Question 1 - 30 What are the divisions of the upper layer of the atmosphere?

  7. Answer 1 – 30 Ionosphere and exosphere

  8. Question 1 - 40 What are the 4 layers of the atmosphere?

  9. Answer 1 – 40 Troposphere, Mesosphere, Stratosphere, and Thermosphere

  10. Question 1 - 50 Why does the temperature of different layers of the atmosphere vary?

  11. Answer 1 – 50 The composition of the gases in the layer absorb solar energy differently.

  12. Question 2 - 10 How much of the sun’s energy is absorbed by the Earth’s surface?

  13. Answer 2 – 10 50%

  14. Question 2 - 20 What is the term for the process of how the gases in the atmosphere absorb thermal energy & radiate it back to Earth?

  15. Answer 2 – 20 Greenhouse Effect

  16. Question 2 - 30 What is the transfer of thermal energy by the circulation or movement of a liquid or gas?

  17. Answer 2 – 30 Convection

  18. Question 2 - 40 How do differences in air density cause convection currents?

  19. Answer 2 – 40 Cold air is more dense so it sinks and the warm air rises

  20. Question 2 - 50 What are the two main human activities that increase the levels of greenhouse gases?

  21. Answer 2 – 50 Burning of fossil fuels and deforestation

  22. Question 3 - 10 List the 3 types of global winds.

  23. Answer 3 – 10 Polar easterlies, Prevailing westerlies, and trade winds

  24. Question 3 - 20 List the 4 types of local winds.

  25. Answer 3 – 20 Sea, Land, Mountain, and Valley breezes

  26. Question 3 - 30 What are the winds that flow towards the poles from W to E between the 30 & 60 degree latitudes?

  27. Answer 3 – 30 Prevailing Westerlies

  28. Question 3 - 40 What weather do the polar easterlies bring?

  29. Answer 3 – 40 Snow and freezing cold

  30. Question 3 - 50 Why does sinking air cause areas of high pressure?

  31. Answer 3 – 50 Sinking air presses down on the air beneath it

  32. Question 4 - 10 How are primary pollutants put into the air?

  33. Answer 4 – 10 Directly by human or natural activity

  34. Question 4 - 20 Name 2 examples of secondary pollutants.

  35. Answer 4 – 20 Smog and ozone

  36. Question 4 - 30 What is formed when sunlight reacts with ozone and vehicle exhaust?

  37. Answer 4 – 30 Smog

  38. Question 4 - 40 What are the 3 sources of human-made air pollution?

  39. Answer 4 – 40 Industrial air pollution, indoor air pollution, and transportation.

  40. Question 4 - 50 How is acid precipitation formed?

  41. Answer 4 – 50 Fossil fuels burn, mix with water vapor, and form sulfuric and nitric acid.

  42. Question 5 - 10 In which 2 atmospheric layers does temperature decrease as altitude increases?

  43. Answer 5 – 10 Troposphere & Mesosphere

  44. Question 5 - 20 What is the transfer of energy as heat through a material? (touching)

  45. Answer 5 – 20 Thermal conduction

  46. Question 5 - 30 What is the movement of air caused by differences in air pressure?

  47. Answer 5 – 30 Wind

  48. Question 5 - 40 What is the curving path of an moving object from an otherwise straight path caused by the Earth’s rotation?

  49. Answer 5 – 40 The Coriolis Effect
