10 Part A Answer all questions in this part. Directions (1 35): For each statement or question, write on your separate answer sheet the number of the word or expression that, of those given, best completes the statement or answers the question. Some questions may require the use of the Earth Science Reference Tables. 5 The diagram below is a constructed ellipse. F1 and F2 are the foci of the ellipse. 1 One complete cycle of the phases of the Moon takes approximately one (1) day (3) month (2) week (4) year 2 The diagram below shows the Moon at four positions in its orbit around Earth. F1 F2 1 Earth 2 North Pole 4 The eccentricity of this constructed ellipse is closest to the eccentricity of the orbit of which planet? (1) Mercury (3) Saturn (2) Earth (4) Pluto Rays from the Sun 6 The diagram below shows the noontime shadow cast by a vertical post located in New York State. 3 (Not drawn to scale) D An observer on Earth could see a solar eclipse when the Moon is at position (1) 1 (3) 3 (2) 2 (4) 4 C A B 3 Which two stars have the most similar luminosity and temperature? (1) Betelgeuse and Barnard s Star (2) Rigel and Betelgeuse (3) Alpha Centauri and the Sun (4) Sirius and Procyon B Which letter indicates a location west of the post? (1) A (3) C (2) B (4) D 4 Which planet would float if it could be placed in water? (1) Mercury (3) Saturn (2) Earth (4) Pluto P.S./E. Sci. Aug On March 21, at which location in New York State would sunrise occur first? (1) Riverhead (3) Buffalo (2) Syracuse (4) Massena [2]

11 Part A Answer all questions in this part. Directions (1 35): For each statement or question, write on your separate answer sheet the number of the word or expression that, of those given, best completes the statement or answers the question. Some questions may require the use of the Earth Science Reference Tables. 1 A Foucault pendulum appears to change its direction of swing over a period of several hours because of Earth s (1) rotation (3) tilted axis (2) revolution (4) gravity 4 The diagrams below represent Earth s ocean tides at four different positions of the Moon. Which diagram shows the Moon position that will produce the highest high tides and the lowest low tides? (The diagrams are not drawn to scale.) Key 2 The same side of the Moon always faces Earth because the (1) Moon s period of rotation is longer than its period of revolution around Earth (2) Moon s period of rotation is shorter than its period of revolution around Earth (3) Moon rotates once as it completes one revolution around Earth (4) Moon does not rotate as it completes one revolution around Earth E = Earth M = Moon H = High tide L = Low tide M H L Sun M H E H Sun L L (3) Sun E H H H L Sun L L M Star F2 (2) L E H M (4) 5 From which New York State location would Polaris be observed to have an altitude closest to 43 above the northern horizon? (1) Binghamton (3) Watertown (2) Utica (4) New York City What is the approximate eccentricity of this ellipse? (1) 0.22 (3) 0.68 (2) 0.47 (4) 1.47 P.S./E. Sci.
