3rd Quarter
New Moon
Full Moon
1st Quarter
11
Why would you weigh less on the Moon than you do on Earth?
Because you are further from the Earth
Your weight would not change
Because you are further from the Sun
Because the Moon has less mass
12
Which statement is true about the planets orbiting the Sun?
Planets closer to the Sun orbit more slowly
Planets closer to the Sun orbit more quickly
Planets with more mass orbit the Sun more slowly
All planets orbit the Sun at the same speed
13
Which of these answers best explains the reasons we see the phases of the Moon?
The angle the Moon makes with the Earth and Sun
The Sun's shadow falling on the Moon
The Moon's shadow falling on the Earth
The Earth's shadow falling on the Moon
14
Orbital motion of the planets around the Sun is caused by interaction between inertia and
strong nuclear force
gravitational force
the Sun's energy
frictional forces
15

Mars
Mercury
Earth
Jupiter
16
During a solar eclipse
the Moon is directly between the Earth and the Sun
the Moon is at a 90 degree angle with the Earth and the Sun
the Earth is directly between the Sun and the Moon
the Sun is blocked by Earth's shadow
17
What best explains why we don't have a total lunar eclipse every time there is a full Moon?
The tilt of the Moon's orbit around Earth
The tilt of the Earth on its axis
The Earth is between the Sun and the Moon during a Full Moon
The Moon is between the Earth and the Sun during a Full Moon

three quarters of it
half of it
all of it
a quarter of it
19
From Earth we always see the same side of the Moon because . . . . .
the Moon has the same period of rotation and revolution
the Moon does not rotate on its axis
the Moon and the Earth rotate at the same rate
the Earth has the same rate of rotation and revolution
20
Which was a major contribution of Copernicus in the development of the Solar System model?
The Moon orbits the Earth
The Sun is the center of our Solar System
The Earth is the center of our Solar System
Constellation all are a part of our Solar System
21
The Moon's gravity has more effect on Earth's tides than the Sun's gravity. Why is this so?
The Sun DOES has a greater effect on Earth's tides.
The Sun is not moving
The Moon is so much closer to Earth
Sun's gravity has no effect on the water on Earth
22
What event causes day and night on Earth?
The angle of Earth's orbit
Earth's rotation
Earth's revolution
The tilt of the Earth on its axis
23
How would standing on the Moon affect your mass?
You would have more mass caused by Eath's gavitational pull
You would have less mass becuase of the distance from Sun
Your mass would not change
You would have less mass because the Moon has less gravity
24
What is the force most responsible for the Moon staying in 'orbit' around the Earth?
magnetism
friction
gravity
strong nuclear force
25
The gravitational force between any two objects is dependent on their
their distances from each other
gravitational constants
their masses and distances they are from each other
their masses
