Why does the moon revolve around the Earth?
The moon is very large
The Earth is very large

The Sun's gravitational force holds the moon near Earth
Gravitational force is strongest when two objects are larger and closer together.
True
False
Gravity is necessary in the formation of:
asteroids
planets
galaxies
all of the above
Mass affects gravitational force because...
The less mass, the more gravitational force
The larger something is, the more gravitational force
The more mass, the more gravitational force
The smaller something is, the more gravitational force
Distance affects gravitational force because...
The closer objects are, the greater the gravitational force
The farther apart objects are, the greater the gravitational force
Tides are caused by:
Wind
Earth's orbit around the sun
Night and Day
The Moon's gravitational pull
If a planet moves closer to the Sun, what happens to the gravitational force between them?
It increases
It decreases
It stays the same
They are still too far apart for gravity
If a planet orbits closer to the sun, what effect will it have on the planet's orbital period (year)?
The planet's orbital period will be longer
The planet's orbital period will be shorter
The planet's orbital period is not affected by distance
All planets have the same orbital period
Which choice best describes the parts of the Milky Way?
Earth, its moon, the sun, and Jupiter
Gas, dust, stars, and objects that orbit stars
Asteroids, comets, objects that orbit stars, and the stars
The inner planets, the outer planets, gas, and dust
