Base your answers to questions 44 through 47 on the diagram below and on your knowledge of Earth
science. The diagram represents the Moon at four positions, labeled A, B, C, and D, in its orbit around Earth.
The position of the full-Moon phase is labeled.
A
Full
Moon
Sun’s
North
B
D
rays
Pole
Key
C
(Not drawn to scale)
Lighted side
Dark side
44 Approximately how many days (d) does it take for the Moon to move from the phase shown at position A
to the full-Moon phase?
(1) 7.4 d
(3) 27.3 d
(2) 14.7 d
(4) 29.5 d
45 Which phase of the Moon could be observed from New York State when the Moon is at position C?
( 1 )
( 2 )
( 3 )
( 4 )
46 The same side of the Moon always faces Earth because the Moon’s period of revolution
(1) is longer than the Moon’s period of rotation
(2) equals the Moon’s period of rotation
(3) is longer than Earth’s period of rotation
(4) equals Earth’s period of rotation
47 Solar and lunar eclipses rarely happen during a cycle of phases because the
(1) Moon’s orbit is circular and Earth’s orbit is elliptical
(2) Moon’s orbit is elliptical and Earth’s orbit is elliptical
(3) plane of the Moon’s orbit is different from the plane of Earth’s orbit
(4) plane of the Moon’s orbit is the same as the plane of Earth’s orbit
