A. a galaxy
B. a planet
C. Earth's Moon
D. another star

4.  Base your answer to the following question on the diagram below which shows the Earth's orbit and the partial orbit of a comet on the same plane around the Sun. Which observation is true for an observer at the Earth's Equator at midnight on a clear night for the positions shown in the diagram?


A. The comet is directly overhead
B. The comet is rising
C. The comet is setting
D. The comet is not visible

5.  The "fuel" of the sun is:
A. hydrogen
B. helium
C. oil and various hydrocarbons
D. oxygen

6.  Base your answer to the following question on the diagram below. The diagram represents the Earth at a position in orbit around the Sun, the Sun's rays at solar noon, and the directions to Polaris. Letters A though D represent positions on the Earth's surface. What is the latitude of position A?


A. 23.5 degrees north
B. 47 degrees north
C. 66.5 degrees north
D. 90 degrees north

7.  The diagram below shows the rotating Earth as it would appear from a satellite over the North Pole. The time at point X is closest to:


A. 6AM
B. 12 noon
C. 6PM
D. 12 midnight

8.  Base your answer to the following question on the diagram below, which represent two vies of a swinging Foucault pendulum with a ring of 12 pegs at its base. The predictable change in the direction of swing of a Foucault pendulum provides evidence that the:


A. Sun rotates on its axis
B. Sun revolves around the Earth
C. Earth Rotates on its axis
D. Earth revolves around the Sun

9.  The diagram below represents two photographs of the Moon, A and B, taken at full moon phase several months apart. The photographs were taken using the same magnification. Each photograph was cut in half and the halves placed next to each other. What most likely caused the difference in the apparent size of the Moon in the photographs A and B?


A. The phases of the Moon changed
B. The Moon expanded
C. The distance for the Earth to the Moon changed
D. The Moon rotated

10.  Base your answer to the following question on the diagram below. The diagram shows twelve constellations that are visible in the night sky to an observer in New York State, over the course of a year. Different positions of Earth are represented by letters A through D. The arrows represent the direction of Earth's motion around the Sun. The constellations observed from New York State when the Earth is at position A are different from the constellatons observed when Earth is at position C because:


A. Earth moves in its orbit
B. Earth is tilted on its axis
C. the lengths of day and night are different
D. the stars move around Earth as shown by star trails
