12. Question 1 - 50 How does the Earth’s atmosphere protect the Earth?

13. Answer 1 – 50 Blocks out harmful UV rays Keeps the Earth at a constant temperature.

14. Question 2 - 10 What is the definition of air pressure?

15. Answer 2 – 10 The force put on a given area by the weight of the air above it.

16. Question 2 - 20 What four factors can change air pressure?

17. Answer 2 – 20 Volume Temperature Humidity Altitude

18. Question 2 - 30 What is the definition of altitude?

19. Answer 2 – 30 The height above the Earth’s surface.

20. Question 2 - 40 Why does the weight of the air pressure pushing down on us not crush us?

21. Answer 2 – 40 Because we have the same amount of air pressure pushing out of us as we do pushing down on us. We are pressurized. The pressures cancel each other out.

23. Answer 2 – 50 205.8 lbs/in 2

24. Question 3 - 10 What are two kinds of local winds? (We didn’t learn about the other two, but if you can write the other correct local winds down you will receive 2 bonus points)

25. Answer 3 – 10 Sea Breeze and land Breeze Mountain Breeze and Valley Breeze

26. Question 3 - 20 What is a Land Breeze?

27. Answer 3 – 20 A land breeze is when air moves from land to water.

28. Question 3 - 30 At what time does a Sea breeze happen?

30. Question 3 - 40 How does wind always blow?

31. Answer 3 – 40 From High Pressure to Low Pressure.

32. Question 3 - 50 Explain how the sun affects local winds.

33. Answer 3 – 50 The sun affects local winds by heating different surfaces at different temperatures. By heating water faster than land.

34. Question 4 - 10 What are global winds?

35. Answer 4 – 10 Global winds are winds that blow steadily over long distances in a predictable direction.

36. Question 4 - 20 Where are trade winds located?

37. Answer 4 – 20 Trade winds are located between 30 N and 30 S

38. Question 4 - 30 What is the Coriolis Effect?

39. Answer 4 – 30 The Coriolis Effect describes the change in direction of something on or above Earth’s surface because of Earth’s rotation.

40. Question 4 - 40 Draw a circle with a line going through the middle. Label which direction global winds blow in the Northern Hemisphere and the Southern Hemisphere.

41. Answer 4 – 40

42. Question 4 - 50 How does the sun affect global winds?

43. Answer 4 – 50 The sun affects global winds because sunlight heats areas near Earth’s equator more than it heats areas near Earth’s poles.

44. Question 5 - 10 What is a barometer?

45. Answer 5 – 10 An instrument that measures atmospheric pressure or air pressure.

46. Question 5 - 20 What is a weather vane?
