Determine whether or not the statement is true or false. If false, edit the sentence so that it is
true.
MAP
___1. The Himalayas are located in Asia, bordering India.
___2. The Andes Mountains are on the eastern side of South America.

___3. Weather is the condition of the bottom layer of the earth’s crust in one place over a
short period of time.
___4. A description of the weather usually mentions temperature, moisture or precipitation,
and wind.
___5. The weather in one region usually has no effect on the weather in other regions.
___6. Climate is the term for weather patterns that an area has over a long period of time.
___7. The climate of an area depends on elevation, latitude, and location in relation to
landforms and bodies of water.
___8. “Climate is what you get, weather is what you expect.”
___9. The sun is not essential for the survival of plants and animals.

___10. If the earth were not on an axis then we wouldn’t have seasons.

___11. The hole in the ozone prevents heat from escaping back into space too quickly.
___12. The earth’s atmosphere has been compared to an umbrella, shielding us from too much
radiation.
___13. The earth completes seven rotations every twenty-four hours, making one week.
___14. The earth spins from west to east, making the sun appear to rise in the east and set in
the west.
___15. A revolution is one complete orbit around the moon.
___16. The earth completes one revolution every 24 hours.
___17. Because the earth is tilted on its axis, the Tropics of Cancer and Capricorn receive the
least amount of sunlight.

___18. Changes in season are marked by the summer and winter equinoxes.
___19. The spring and fall equinoxes usually occur in April and October.
___20. The sun’s rays always fall most directly at or near the Equator.
___21. Places near the poles are colder because the sun’s rays fall most directly on them.
___22. Latitude, or distance from the Equator, divides the world into zones.
___23. Temperate zones have a wide range of temperatures and distinctive seasons.
Page 66
___24. The sun’s heat is distributed by ocean currents.
___25. Warm air or liquids tend to rise, while cool air tends to sink, except in water.
___26. Rising warm air creates areas of low pressure, falling cool air causes areas of high
pressure.
___27.If the world stopped rotating the winds would blow in straight lines toward the poles.
MAP
___28. The United States is located in the Middle Latitudes, receiving Easterlies for wind.
Page 77
___29. Trade winds blow unpredictably toward the Equator from northeast and southeast.
___30. The ocean currents also help distribute heat, similar to those of winds.
___31. Precipitation is the amount of water vapor contained in the atmosphere.
Page 78
___32. Convectional precipitation occurs when cool, dry air rises from the earth’s surface and
heats up thereby losing its ability to hold water.
___33. Geographic precipitation would occur over a mountain range, when moist air is force
upwards causing precipitation as it cools in the higher altitude.
___34. The land on the leeward side of the mountains, away from the wind, lies in what is
called a rain doggy.
___35. Frontal precipitation occurs when two fronts meet, the warm air is forced upward by
the heavier cool air.
___36. Other influences on climate include nearby bodies of water, longitude, elevation, and
location in relation to nearby landforms.

___37. Water temperatures change much more slowly than land temperatures.
___38. Winds that blow over water take on the water’s temperature as they blow onshore.
___39. Continental climates have mild, dry winters and cool or cold summers.
___40. It is impossible to have snow on or near the Equator.
Page 70-71
___41. Air temperature decreases at a rate of about 35 degrees for every 1,000 feet in
elevation.
___42. A concentration of tall buildings can influence climate in the surrounding area.
___43. Determining climate regions rely on elevation and latitude.
MAP
___44. The climate of Utah can be classified as arid, semiarid AND highland.
___45. The climate of Canada (away from the U.S. border) is mostly Tundra, Ice Cap, and
Mediterranean.
___46. Along the Equator the climate is Tropical Wet and Dry.

47. Choose the most ideal climate for you and explain why you chose it.
Page 73
___48. Increasing amounts of hydrogen peroxide and other substances in the earth’s
atmosphere lead to what scientists call “global warming.”
___49. Global warming could partially melt polar ice caps, causing a rise in the level of the
oceans and flooding the densely populated low-lying areas.
50. Sketch the diagram of Global Warming below.
