Solar System Practice Test Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. 1. Day and night are caused by a. the tilt of Earth’s axis. b. Earth’s revolution around the sun. c. eclipses. d. Earth’s rotation on its axis. 2. One complete revolution of Earth around the sun takes about a. one rotation. b. one season. c. one year. d. one eclipse. 3. Earth has seasons because a. Earth rotates on its axis. b. the distance between Earth and the sun changes. c. Earth’s axis is tilted as it moves around the sun. d. the temperature of the sun changes. 4. When the north end of Earth’s axis is tilted toward the sun, North America will experience a. more indirect rays and shorter days. b. more indirect rays and longer days. c. more direct rays and shorter days. d. more direct rays and longer days. 5. The phase of the moon you see depends on a. where you are on Earth’s surface. b. how much of the sunlit side of the moon faces Earth. c. how much of the moon’s surface is lit by the sun. d. whether or not an eclipse is occurring. 6. From new moon phase to full moon phase you see a. an increasing amount of the lighted side of the moon. b. a decreasing amount of the lighted side of the moon. c. the same amount of the lighted side of the moon. d. more of the lighted side, then less of the lighted side of the moon. 7. For a solar eclipse to occur, a. the sun must be directly between Earth and the moon. b. the moon must be directly between Earth and the sun. c. the moon must be directly behind Earth. d. Earth must be directly between the sun and the moon. 8. During what phase can a lunar eclipse occur? a. new moon b. first quarter c. waxing gibbous d. full moon 9.

Tides are caused mainly by a. Earth’s rotation on its axis, which causes water to move. b. differences in how much the sun pulls on different parts of Earth. c. strong winds blowing water onto coasts. d. differences in how much the moon pulls on different parts of Earth. 11. How large is the moon compared to Earth? a. about the same diameter as Earth b. about one half the diameter of Earth c. about one fourth the diameter of Earth d. about one eighth the diameter of Earth 12. Earth’s rotation takes about a. 365 days. b. 6 months. c. 24 hours. d. 1 month. 13. Because the moon rotates once for each revolution around Earth, a. you see some phases more than others. b. a different side of the moon faces Earth each day. c. you never see the far side of the moon. d. the far side of the moon is visible only during the full moon phase. 14. The amount of the lighted side of the moon you can see is the same during a. new moon and full moon phase. b. new moon and first quarter phase. c. first quarter and third quarter phase. d. full moon and third quarter phase. 15. You are more likely to see a solar eclipse than a lunar eclipse because a. the moon’s shadow covers all of Earth during a solar eclipse. b. new moon phases occur less often than full moon phases. c. only people on the daytime side of Earth can see a solar eclipse. d. you must be in the moon’s shadow to see a solar eclipse. 16. When do neap tides occur? a. at new moon b. when the sun’s pull is in the same direction as the moon’s c. when the sun’s pull is at right angles to the moon’s d. at full moon 17. The sun produces energy by a. attracting it with the force of gravity. b. nuclear fission. c. burning fuels such as oil. d. nuclear fusion. 18. There is enough fuel remaining in the sun to last for another a. 1 billion years. b. 5 billion years. c. 10 billion years. d. 15 billion years. 19.
