  • 1. Name:_____________________________________________________________ Period:____________ Date:________________Unit 2: Astronomy Seasons & Suns Path 1. the diagram below, which shows a model of Earth’s orbit around the Sun. Two motions of Earth are indicated. Distances to the Sun are given for two positions of Earth in its orbit. Explain why Canada experiences summer when Earth is at its greatest distance from the Sun. 2. Which model best represents the apparent path of the 4. Which diagram correctly shows the directions of Sun observed at various times during the year at the Earths revolution and rotation? Equator? 1) 1) 2) 2) 3) 4) 3) 3. Which statement best describes the position of the Sun at sunrise and sunset as seen by an observer in New York State on June 21? 4) 1) The Sun rises north of due east and sets south of due west. 2) The Sun rises south of due east and sets south of due west. 3) The Sun rises north of due east and sets north of due west. 4) The Sun rises south of due east and sets north of due west.

  • 2. 5. The diagram below shows Earth as viewed from space. Which season is beginning in the Northern Hemisphere? 1) summer 2) winter 3) fall 4) spring6. Base your answer to the following question on the diagram below, which shows Earth and the Moon in relation to the Sun. Positions A, B, C, and D show the Moon at specific locations in its orbit. Point X is a location on Earths surface. On what date does the line separating day and night pass through Earths North Pole, as shown in this diagram? 1) June 21 2) December 21 3) January 21 4) March 217. Which two factors cause the perpendicular rays of 8. At which latitude is the Sun directly overhead on the Sun to move between 23.5º N and 23.5º S? certain days of the year? 1) tilt of Earths axis and Earths revolution 1) 42° N 2) 23.5° N 2) eccentricity of Earths orbit and Earths 3) 66.5° N 4) 90° N revolution 3) eccentricity of Earths orbit and Earths rotation 4) tilt of Earths axis and Earths rotation Page 2
  • 3. 9. Base your answer to the following question on the diagram below, which represents Earth in its orbit around the Sun. The position of Earth on the first day of each season is labeled A, B, C, and D. What is the approximate rate of Earths revolution around the Sun? 1) 15° per year 2) 15° per day 3) 1 ° per year 4) 1 ° per day10. Base your answer to the following question on the diagrams below, which show the apparent path and solar noon positions of the Sun on specific dates at three different locations on Earth. What evidence indicates that the observer at location A is at the equator?11. Which motion causes the constellation Orion to be 13. The diagram below shows the noontime shadows visible at midnight from New York State in winter but cast by a student and a tree. not in summer? 1) revolution of Orion 2) rotation of Orion 3) revolution of Earth 4) rotation of Earth12. If the axis of Earth were not tilted relative to the plane of its orbit around the Sun, the result would be 1) a reversal of polar and equatorial climates 2) an equal number of hours of daylight at most locations 3) a greater number of hours in a day 4) a greater number of days in a year If the time is solar noon and the student is located in New York State, in what direction is the student facing? 1) west 2) south 3) east 4) north Page 3
  • 4. 14. Base your answer to the following question on diagram below, which represents the Sun’s apparent paths and the solar noon positions for an observer at 42 ° N latitude on December 21, September 23, and June 21. Which graph best shows the altitude of the Sun, as measured by the observer located at 42 ° N, at various times on December 21? 1) 2) 3) 4) Page 4
  • 5. 15. Base your answer to the following question on the diagram below which shows twelve constellations that are visible in the night sky to an observer in New Jersey, over the course of a year. Different positions of Earth are represented by letters A through D. The arrows represent the direction of Earths motion around the Sun. Which constellations are both visible at midnight to an observer in New Jersey when Earth is located at position D? 1) Aries and Taurus 2) Pisces and Libra 3) Aquarius and Scorpio 4) Leo and Virgo16. The diagram below shows the shadow cast by a telephone pole on March 21 at solar noon at a location in New York State. Which shadow was cast by the same telephone pole on June 21 at solar noon? 1) 2) 3) 4) Page 5
  • 6. 17. Base your answer to the following question on the diagram below, which shows a model of Earth’s orbit around the Sun. Letters A, B, C, and D represent Earth’s position at the beginning of each season. How many degrees will the Sun’s vertical rays shift on Earth’s surface as Earth travels from position C to position D? 1) 15° 2) 23.5° 3) 47° 4) 365° Base your answer to questions 18 through 20 on the diagram below, which represents Earth revolving around the Sun. Letters A, B, C, and D represent Earths location in its orbit on the first day of the four seasons. NP represents the North Pole.18. If the tilt of Earths axis were decreased from 23.5 ° to 15°, New York States winters would become 1) cooler, and summers would become cooler 2) cooler, and summers would become warmer 3) warmer, and summers would become warmer 4) warmer, and summers would become cooler Page 6
  • 7. 19. Which diagram best represents the Suns apparent path as seen by an observer at 43.5° N latitude on December 21? 1) 2) 3) 4)20. Which location in Earths orbit represents the first day of summer in New York State? 1) A 2) B 3) C 4) D Base your answer to questions 21 and 22 on the graph below, which shows the duration of daylight hours throughout the year for five cities located in the Northern Hemisphere.21. Which city experiences the greatest variation in daylight hours during one year? 1) Caracas 2) New Orleans 3) Mexico City 4) Edmonton Page 7
  • 8. 22. What is the primary reason each city’s duration of daylight hours changes throughout the year? 1) The cities are located at different longitudes. 2) The cities are located at different elevations. 3) Earth’s rotation rate is 15° per day. 4) Earth’s axis is tilted 23.5 ° to the plane of its orbit.23. Base your answer to the following question on on the diagram below, which shows the parts of Earth experiencing daylight and darkness as Earth orbits the Sun. Letters A, B, C, D, and E are positions in Earths orbit as viewed from above the Northern Hemisphere. On the grid, place Xs to show the duration of insolation at the Arctic Circle (66.5º N) as Earth orbits the Sun at positions A, B, C, and D. Connect the Xs with a line. Page 8
  • 9. 24. Which graph best represents the average monthly temperatures for one year at a location in the Southern Hemisphere? 1) 2) 3) 4)25. A student in New York State looked toward the eastern horizon to observe sunrise at three different times during the year. The student drew the following diagram that shows the positions of sunrise, A, B, and C, during this one-year period. Which list correctly pairs the location of sunrise to the time of the year? 1) A—December 21 B—March 21 C—June 21 2) A—June 21 B—December 21 C—March 21 3) A—March 21 B—June 21 C—December 21 4) A—June 21 B—March 21 C—December 21 Page 9
