If you are in the moon’s
umbral shadow you will
experience a ______ _______
eclipse
$800
Total solar eclipse
Which eclipse occurs at a new
moon on the ecliptic near
perigee?
$1000
The moon’s orbit is not a perfect circle. When the
Moon is closer to Earth it is big enough to cover the
sun completely if it is too far away it appears smaller
so a ring of sunlight is around it.
Why are some solar eclipses total and others
annular?
$200
7 PM
What time will the moon rise
tomorrow if it rises tonight at
6 pm?
$400
the Earth is also revolving around the sun
so the moon catches up
Why is there a two day
difference between sidereal
and synodic months?
$600
equals
The moon’s rotational
period___________ its
orbital period?
$800
Full. it is rising opposite
the sun.
What phase will the moon be if it is
rising at sunset? Why?
$1000
waxing gibbous,1 pm
The first quarter moon rises about noon
today, what phase and time will it rise
tomorrow?
$200
Full
When the moon is opposite
the sun, the phase is?
$400
Waning gibbous
Driving eastward before
sunrise you notice the moon
in front of you, what phase is
it?
$600
The gravitational force of the Earth
on the moon has slowed the
moon’s rotation so that it rotates
once during each revolution so that
the one face always faces toward
the Earth
What is meant by tidal
locking?
$800

thinner.

Why?

Lunar highlands , cratering tells us it is older.
Which is older the lunar highlands or the
maria? How do we tell?
$400
lunar highlands
Due to cratering we can tell that
this area of the moon is 4.6 to
4.4 billion years old?
$600
The moon lacks wind, water and atmosphere
Why is there less erosion on
the moon than earth?
$800
The longer a surface has not had internal
deformation like lava flows, the more
craters that will form on its surface.
how does crater counting allow us to estimate ages
of surfaces in the Solar System?
$1000
Meteroite and micrometerioite bombardment forming a thick layer of
dust
What are the primary sources of
erosion on the Moon today?
