1 FINAL REVIEW: ASTRONOMY *Base your answers to questions 5-7 the diagram below which shows the position of Earth and four positions of the Moon during one orbit of Earth. 5. On the diagram, draw an X to show where the Sun would need to be located to create the Moon phases shown. 6. Which letter in the diagram shows the position of the Moon when an observer on Earth sees a full Moon? 7. What motion is represented by the arrows in the diagram? _________________________ 1. Which body in our solar system is classified as a star? (1) Earth (2) Mars (3) Venus (4) Sun 2. The diagram below shows Earth, as viewed from space, as it moves around the Sun. Approximately how long does it take Earth to move from position A to position B? (1) 1 year (2) 6 months (3) 1 day (4) 12 hours 3. The Sun appears to move across the sky during the day. The best explanation for this apparent motion is that Earth is: (1) rotating on its axis. (2) revolving around the Sun. (3) much smaller than the Sun. (4) tilted on its axis. X POSITION C REVOLUTION

2 The differences shown in the student’s drawings are 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 Earth 9. The length of a year is equivalent to the time it takes for one (1) rotation of Earth (2) rotation of the Sun (3) revolution of Earth around the Sun (4) revolution of the Sun around Earth 8. 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 solar system as seen from space. For which object is the lighted surface shown incorrectly? (1) Moon (3) Venus (2) Mercury (4) Earth

3 10. The diagram below shows Earth as seen from space. Letters A through D are locations on Earth’s surface. When Earth is in this position, which location would experience the greatest number of day- light hours? (1) A (2) B (3) C (4) D 11. The diagram below shows Earth as viewed from space. Which season is occurring in the Northern Hemisphere? (1) summer (3) winter (2) autumn (4) spring 14. The diagram below shows four objects and their orbits around the Sun, as seen from space. Which statement is true about all of the objects shown in the diagram? (1) They produce their own light. (2) They belong to our solar system. (3) They are composed mostly of gases. (4) They are the same distance from the Sun. 15. The diagram below shows four Moon phases observed during July. On which date would the next New Moon occur? (1) August 5 (3) August 19 (2) August 10 (4) August 29

4 12. Which statement best explains why the Sun & the Moon appear to be about the same size in the sky? (1) The Sun & the Moon have the same diameter. (2) The Moon is larger in diameter & farther from Earth than the Sun. (3) The Moon is smaller in diameter &is closer to Earth than the Sun. (4) The Sun &the Moon are the same distance from Earth. 13. The Moon is visible from Earth because of (1) reflected sunlight (2) absorbed light from Earth’s atmosphere (3) gases in the Moon’s interior (4) volcanic eruptions on the Moon’s surface 16. The streaks in the time-lapse photograph below show the apparent motion of the stars around the North Star during one hour. This apparent motion of the stars can best be explained by Earth’s (1) rotation on its axis (2) tilted axis (3) revolution around the North Star (4) changing distance from the North Star
