1FINAL REVIEW: ASTRONOMY 1. Which body in our solar system is classified as a star?(1) Earth (2) Mars (3) Venus (4) Sun2. The diagram below shows Earth, as viewed from space,as it moves around the Sun.*Base your answers to questions 5-7 the diagrambelow which shows the position of Earth and four positions of the Moon during one orbit of Earth.X5. On the diagram, draw an X to show where theSun would need to be located to create the Moon phases shown.6. Which letter in the diagram shows the positionof the Moon when an observer on Earth sees a fullMoon?7. What motion is represented by the arrows inthe diagram? _________________________Approximately how long does it take Earth to move fromposition A to position B?(1) 1 year (2) 6 months (3) 1 day (4) 12 hours3. The Sun appears to move across the sky during theday. The best explanation for this apparent motion isthat Earth is:(1) rotating on its axis. (2) revolving around the Sun.(3) much smaller than the Sun. (4) tilted on its axis.POSITION CREVOLUTION
28. A student drew pictures to show how the Moon looked from Earth over a two-week period.4. The diagram below shows a portion of the solarsystem as seen from space. For which object is thelighted surface shown incorrectly?The differences shown in the student’s drawingsare mostly due to the changing(1) distance between Earth and the Moon(2) speed of the Moon in its orbit(3) position of the Moon in its orbit(4) position of the observer on Earth9.
