Vocabulary
Define ozone.
Ozone is a form of oxygen that has three oxygen atoms in each molecules instead of the usual two.
What are clouds made out of?
Clouds are made out of tiny drops of water vapor. Water vapor collects in the air and eventually will get to heavy and fall back to Earth.
Most airplanes fly in this layer of the atmosphere.
Stratosphere. There are few things that happen here so it is very calm and there is less turbulence.
Air pressure is......
The result of the weight of a column of air pushing down on an area.
How many layers are ther in out atmosphere?
There are 4 layers. They are classified according to temperature
Define Altitude.
Altitude, or elevation, is the distance above sea level, the average level of the surface of the oceans. The higher you go the more altitude you have.
True or false
There is only one type of cloud.
False. There are many types of clouds and they are all different from each other.
This layer is in the middle. What is it called?
Mesosphere. Fun fact is that meteors burn up in this layer and keep us safe.
What are the most common barometer.
Mercury barometer and aneroid barometer
What does The Ozone layer do for all living things
It helps blocks UV rays from hitting earth
Define atmosphere.
Earth’s atmosphere is the envelope gases that surrounds the planet.
This cloud extends through all levels, thy also make rain and make a storm. What cloud is this?
This is a Nimbus cloud.
This is were Aurora borealis also known as northern lights appear
These happen in the thermosphere.
True or false
Air is more dense when you are closer to sea level
True
How much oxygen is in our atmosphere?
21% of our atmosphere has oxygen in it.
Define water vapor.
Water vapor is water in the form of gas. Water vapor is invisible and is made up of tiny droplets of water.
What part of the atmosphere are clouds in?
Troposphere. Most of weather happens here.
Were do satalites in the atmosphere?
In the exosphere. The exosphere is the top portion of the thermosphere
How does an mercury barometer work?
A mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. The space above the mercury is almost a vacuum- it contains very little air. Greater air pressure forces the column of mercury higher.
True or false
There is neon in our atmosphere.
True. About 0.0018% of our atmosphere is neon
Define barometer.
A barometer is an instrument that is used to measure air pressure. The two most common barometers are the mercury barometer and the aneroid barometer.

What level does a cirrus cloud appear in?
Cirrus clouds appear in the high level of clouds and are very wispy and made up of ice crystals.( all the facts in this category are from my science notes)
Where is the ionosphere?
It is the bottom part of the thermosphere.
(Sources for this subject is from out science text book)
How does an aneroid barometer work?
It has a air tight metal chamber that is sensitive to changes in air pressure. When air is thin the wall are pushed in. The opposite happens for thick air. This chamber is connected to a dial and springs and leversthat help show the air pressure on the dial.

What is the equation for density?
Density= mass/volume
( These fun facts are from out science text book)
