Answer each question by selecting the correct blue button. Only the first answer selected is graded.

1.  Base your answer to the following question on the diagram shown below. Eventually the sun is expected to become a:


A. white dwarf
B. blue supergiant
C. neutron star
D. black hole

2.  Base your answer to the following question on the Earth Science Reference Tables and the diagram below. The diagram represents a model of the Earth-Moon system as viewed from above the North Pole. The numbers 1 though 8 represent positions of the Moon as it revolves around the Earth. The parts of the diagram lettered A through D show how the Moon's phases appear to an observer in New York State. As the Moon's phases changes from first quarter to last quarter, the visible portion of the Moon as observed from Earth will:


A. decrease, only
B. increase, only
C. decrease, then increase
D. increase, then decrease

3.  Base your answer to the following question on the Earth Science Reference Tables and the diagram below. The diagram represents a model of the orbit of a moon around a planet. Points A,B,C, and D indicate four positions of the moon in its orbit. Points F1 and F2 are focal points of the orbit. For an observer on the planet, at which position in the moon's orbit does the full-moon phase occur?


A. choice (A)
B. choice (B)
C. choice (C)
D. choice (D)

4.  The new-moon phase occurs when the Moon is positioned between the Earth and the Sun. However, these positions do not always cause an eclipse(blocking) of the Sun because the:
A. Moon's orbit is tilted relative to the Earth's orbit
B. new-moon phase is visible only at night
C. night side of the Moon faces toward the Earth
D. apparent diameter of the Moon is greatest during the new-moon phase

5.  Base your answer to the following question on the Earth Science Reference Tables, the diagram below, and your knowledge of Earth science. The diagram shows a portion of the solar system. The actual orbits of the planets are:


A. elliptical, with Earth at one of the foci
B. ellipical, with the Sun at one of the foci
C. circular, with the Earth at the center
D. circular, with the Sun at the center

6.  The diagram below represents a student's constructed laboratory drawing. The student's drawing best represents the:


A. shape fo the Earth's Moon
B. shape of an elliptical orbit
C. path of an earthquake wave
D. path of a projectile deflected by Earth's rotation

7.  Base your answer to the following question on the Earth Science Reference Tables, the diagram of the solar system below, and your knowledge of Earth science. According to Kepler's Harmonic Law of Planetary Motion, the farther a planet is located from the Sun, the:


A. shorter its period of rotation
B. shorter it period of revolution
C. longer its period of rotation
D. longer its period of revolution

8.  The diagram below illustrates three stages of a current theory of the formation of the universe. A major piece of scientific evidence supporting this theory is the fact that wavelengths of light from galaxies moving away from Earth in stage 3 are observed to be:


A. shorter than normal (red shift)
B. shorter than normal (blue shift)
C. longer than normal (a red shift)
D. longer than normal (a blue shift)

9.  According to what astronomers have observed to date, the further a galaxy is away from us:
A. the slower it is moving away from us
B. the faster it is moving away from us
C. the slower it is moving towards us
D. the faster it is moving towards us

10.  The graph below represents the brightness and temperature of stars visible from Earth. Which location on the graph best represents a star with average brightness and temperature?


A. choice (A)
B. choice (B)
C. choice (C)
D. choice (D)
