Moon phases Test Review UPDATED
ACTUAL Questions and CORRECT
Answers
Phases of the moon - CORRECT ANSWER - The lunar phase or phase of the moon is the
shape of the illuminated (sunlit) portion of the Moon as seen by an observer on Earth. The lunar
phases change cyclically as the Moon orbits the Earth, according to the changing positions of the
Moon and Sun relative to the Earth.
Where did the moon come from - CORRECT ANSWER - Impact theory - The Moon
formed during an impact between the Earth and another small planet, about the size of Mars. The
debris from this collision collected in an orbit around Earth to form the Moon.
Tides - CORRECT ANSWER - the alternate rising and falling of the sea, usually twice in
each lunar day at a particular place, due to the attraction of the moon and sun.
Lunar eclipse - CORRECT ANSWER - A lunar eclipse occurs when the Moon passes
directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and
Moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle. Hence, a
lunar eclipse can only occur the night of a full moon.
Solar eclipes - CORRECT ANSWER - As seen from the Earth, a solar eclipse is a type of
eclipse that occurs when the Moon passes between the Sun and Earth, and the Moon fully or
partially blocks ("occults") the Sun. This can happen only at new moon, when the Sun and the
Moon are in conjunction as seen from Earth in an alignment referred to as syzygy.
Gravity - CORRECT ANSWER - the force that attracts a body toward the center of the
earth, or toward any other physical body having mass. For most purposes Newton's laws of
gravity apply, with minor modifications to take the general theory of relativity into account.
moon phases - CORRECT ANSWER - The changing appearances of the Moon as seen
