21. Tornadoes

22. Which breeze is shown below?

23. Sea Breeze: During the day, warm air rises over the land, allowing the cooler air from the water to blow in.

24. What powers the water cycle?

25. The SUN!

26. Which step of the water cycle is described below? Water is heated and changes from a liquid to a gas

27. Evaporation: When water is heated and changes from a liquid to a gas

28. Air pressure and density decrease as ___________ increases, making it harder to breathe high up in the mountains.

29. Altitude

30. Which area on the Earth gets the most direct sunlight (solar radiation) all year long?

31. Near the equator

32. What is the protective envelope of gases that surround Earth?

33. Atmosphere

34. What is the main reason that we have four different seasons where we live?

35. Because the Earth is tilted on its axis so, different areas on Earth are tilted towards the sun at different times of the year.

36. In which layer of the atmosphere does our weather take place?

37. Troposphere

38. Where do the warm, moist air masses that move toward us develop (come from)?

39. Gulf of Mexico

40. What provides Earth’s energy?

41. The Sun

42. What are the three things that can happen to the energy that comes from the sun?

43. Absorbed by the atmosphere Absorbed by the land and water Reflected by into space

44. What is the term that refers to the pattern of weather that occurs in an area over many years?

45. Climate

46. What are the three types of heat transfer that work together to warm the troposphere?

47. Conduction Convection Radiation

48. What is the force pushing down on an area or surface?

49. Air pressure

50. What is the natural process where gases hold heat in the air under a “blanket” in the atmosphere, helping to keep Earth’s temperature constant and comfortable for living things?

51. Greenhouse Effect

52. What is the name of the currents created when warm air rises and cooler air moves down—this cycle repeats over and over to balance the changing temperatures?

53. Convection currents

54. Where is the ozone layer found?

55. In the Stratosphere

56. Which layer of the atmosphere protects Earth from most meteoroids?

57. Mesosphere

58. Which clouds are fluffy, rounded cotton-like clouds that are seen on sunny days?

59. Cumulus

60. What is a huge body of air that has similar temperature, humidity & air pressure at any height called?

61. Air mass

62. What always follow lightning?

63. Thunder

64. Which storm forms from similar clouds that bring thunderstorms, occur in the spring & summer, and are described as whirling, funnel-shaped clouds that reach from the storm cloud to the ground?

65. Tornado

66. Which air mass forms over oceans and may be tropical or polar?

67. Maritime

68. Which term refers to any form of water that falls from clouds and reaches Earth’s surface?

69. Precipitation

70. What is the name for the area in the mid U.S. where as many as 800 tornadoes occur each year due to the meeting of warm, moist air from the Gulf of Mexico & cold, dry air from Canada?

71. Tornado Alley

72. How does hail form?

73. Round pellets bounce around inside thunderstorm clouds

74. What is the name of the type of scientist who study the causes of weather and try to make predictions using maps, charts, and computers?

75. Meteorologists

76. Because the Earth’s axis is tilted, the seasons change as different hemispheres receive more or less direct sunlight. When it is winter in the southern hemisphere, what season is it in the northern hemisphere?

77. Summer
