Why do planets orbit the Sun?
The Sun is the only celestial object that has a gravitational pull.
The Sun’s chemical composition makes it attract planets.
Only celestial bodies that emit light, like the Sun, can be at the center of an orbit.
The Sun is the most massive object in our solar system, so it exerts the greatest gravitational pull.

Supergiants
Main Sequence
Giants
Where do comets originate?
Kuiper Belt
Asteroid Belt
The Sun
What is the definition of a dwarf planet?
A dwarf planet is a solar system body that has a spherical shape and an orbit around the Sun that is not cleared of other objects.
A dwarf planet is a small planet that is smaller than Mars.
A dwarf planet is a planet that is further than 2 AU from its orbiting star.
What must happen in order for a satellite to orbit Earth?
The satellite's forward motion must be less than the gravitational pull on it from Earth
The forward motion of the satellite must be balanced by the pull of gravity from Earth
It's not possible for a satellite to orbit Earth
Earth's gravity must be stronger

How are air masses form into clouds? Clouds are form when
cold moist air rises and then cools
warm moist rises, expands and then cools
cold air reaches the lifted condensation level
The temperature at which the air become completely saturated with water vapor is called
humidity
dew point
air density
air pressure
Humidity is the
air density from cold air masses
amount of air pressure in the air.
amount of water vapor present in the air.
concentration of water vapor that form clouds in the air.
Warm air tends to ______
Rise
Sink
One way to get water vapor to condense from the air include
Cooling the air down
Warming the air up
Where is the humidity likely to be higher?
At low elevations
At higher elevations
How does the temperature change as you go up in elevation?
The temperature gets colder as you go up
The temperature gets warmer as you go up
The temperature stays the same as you go up
If warm air and cold air both have same amount of water vapor, which has a lower relative humidity?
Cold air
Warm air
When someone refers to 'dry air', what they really mean is _______ .
high humidity air
hot air
cold air
low humidity air
Why is cold air is drier than warm air?
because there is less room for water molecules.
because the water molecules are more likely to condense to a liquid.
because it cannot hold any water.
because it is too dense.
An air mass is a large mass of air that is defined by its temperature and ____________________.

Hurricanes, overuse of groundwater, and water pollution.
El niño, hurricanes, and ocean evaporation.
How do oceans influence the temperature of the tropics and poles?
They keep it warm by brining more rain.
They help to distribute heat to the poles.
The oceans do not play a role in temperature.
