-Which TWO of the following statements are CORRECT with
respect to the synodic period of the moon?
The synodic and sidereal periods would still be different
lengths of time if the Earth did not revolve around the sun and was
stationary in space with respect to the sun.
The synodic period of the moon is easy to observe if you are
so inclined.
The synodic period equals 27.3 days.
The synodic period of the moon is equal to one rotation of the
moon around its axis.
The synodic period equals the orbital period of the moon
around the Earth.
The synodic period regulates the beat for solar
eclipses.
-Any central solar eclipse Two answers are CORRECT.
always involves the Earth’s shadow.
must happen at least twice each year.
has very little chance of passing through Bethlehem, PA.
could happen as many as six times a year.
could be annular or total.
-PICK THE BEST ANSWER. The ecliptic represents
all of the possible answers.
the intersection positions of the celestial equator (vernal
and autumnal equinoxes).
the projection of Earth's orbit into space.
the region of the sky where eclipses can take place.
the location of the moon when it is at a node.
the plane which is created by the motion of the sun due to
Earth's revolution.
-The lower limit (4) regarding the number of solar plus lunar
eclipses that must occur each year results from the fact that
there are two nodes, the ascending node and descending node
and one lunar and one solar eclipse must occur at each node.
the moon and the sun have two extremes with respect to their
distance from the Earth.
the week is composed of only seven days. If the week had more
days, the number of eclipses happening in one year would be
greater.
the moon’s orbit lies in the plane of the ecliptic.
It is possible for an eclipse to occur before and after the
node therefore creating the two possible eclipses.
-If the moon's orbit was exactly in the plane of the ecliptic,
Earth’s orbit, and not titled by five degrees, approximately one
lunar and one solar eclipse would occur
twice each year.
once in every 18.61 years.
seven times each year.
each month.
twice each month.
once each year.
