C) Temperatures would be constant year
round.

9.
As Earth spins on its axis, producing night and
day, it also moves about the Sun in an

Study the surface from the moon,
since it is closer to Jupiter.
7. The planet Neptune is larger than the
planet Venus. Yet you and I can see Venus
with the naked eye, and definitely with a pair
of binoculars. But for us to see Neptune, we
would need a strong telescope. This is
because
A)Neptune is on the opposite side of the sun
B) of our position on the surface of the Earth.
C) most of Neptune's mass is gas and we
cannot see gas.
D )Neptune is so far from Earth and Venus is
much closer.
8. Why does Earth orbit the Sun rather than
any other body in the solar system?
A)The mutual repulsions among all the
planets hold Earth in its orbit.
B)The Earth is closer to the Sun than other
bodies in the solar system.
C)The Sun is the most massive object;
gravitational attraction is related to mass.
D)The rotational motions of all the planets,
including Earth, cause them to remain in its
orbit around the Sun.
9.Hundreds of years ago, it was believed by
many that our solar system was Geocentric.
This means that Earth is at the center of the
solar system, with the Sun and other planets
orbit around it. Today, the solar system is
now thought to be Heliocentric.
What does this mean?
A)The Sun and other planets orbit Earth.
B)Earth and all the other planets orbit the
Sun.

New
B)
Waxing Crescent
C)

Full
7 A total solar eclipse is a rare event. Although
they occur somewhere on Earth every 18
months on average, it is estimated that they
recur at any given place only once every 370
years. Why are reoccurring solar eclipses so
rare?
A) Because of the rotation of the moon and
earth, the three rarely form a straight line.
B) The light from the sun usually passes
through the moon instead of being blocked by
it.
C) A total solar eclipse actually occurs
monthly, but is only visible from the the
equator.
D )The Moon passes slightly above or below
the line between the Sun and the Earth
because of its tilted orbit.

20%
C)
