One complete revolution of Earth around the sun takes about a. one day. c. one year. b. one season. d. one month ______ 2. a. b. c. d. ______ 3. In the Southern Hemisphere, the summer solstice occurs when the sun is a. at the equator. c. farthest north. b. farthest south. d. closest to Earth. ______ 4. All objects are attracted to each other by the force of a. weight. c. inertia. b. mass. d. gravity. ______ 5. a. b. c. d. ______ 6. A pattern or grouping of stars imagined by people to represent a figure is a a. star chart. c. seasonal pattern. b. mythological object. d. constellation. ______ 7. The tendency of a moving object to continue moving in a straight line or a stationary object to remain in place is called a. orbital speed. c. inertia. b. mass. d. gravity. ______ 8. a. b. c. d. ______ 9. During a total lunar eclipse the moon is in Earth’s a. shadow. c. rotation. b. weather. d. orbit. ______ 10. How long does it take the earth to rotate one time? a. day b. month c. year Earth has seasons because it rotates on its axis. the distance between Earth and the sun changes. its axis is tilted as it moves around the sun. the temperature of the sun changes. The strength of the force of gravity depends on the masses of the objects and their speeds. the masses of the objects and the distance between them. the weight of the objects and their speeds. the masses of the objects and their weights. The phase of the moon you see depends on where you are on Earth’s surface. how much of the sunlit side of the moon faces Earth. how much of the moon’s surface is lit by the sun. whether or not an eclipse is occurring. 1 Chapter Tests © Pearson Education, Inc., or its affiliates.
