1. My family and I flew to Hawaii for winter break. After the plane took off, as
we got further from Earth’s surface, or, the higher in
___________________________ , my ears began to pop.
2. My ears were popping because as we flew higher the weight of the air on my
ears, or the ___________________________ was decreasing.
3. Earth is the only planet in our solar system that is suitable for life because it has an
___________________________ that surrounds Earth like a blanket.
4. As Neil Armstrong walked across the Moon, it seemed as though he was almost floating. This is
because there is less of a force of ___________________________ on the Moon.
5. I didn’t know what to wear to school today so I went outside to use my thermometer. The
thermometer tells me the ___________________________ , which is a measurement of the movement
of air particles. The faster the air particles are moving, the warmer it is outside.
6. Unfortunately, there is certain pollution in our atmosphere that can damage the
___________________________, which helps protect Earth from harmful radiation.
7. Nitrogen makes up 78% of the ___________________________ that we breathe.
8. I was watching the weather yesterday and the meteorologist said there was a
___________________________ system coming to Loudoun. I knew this meant it was going to be
colder outside.
9. When hikers climb Mount Everest they must carry an oxygen tank with them. This is because the
___________________________ decreases as you travel higher in the atmosphere.
10. When a ___________________________ system is in our area, the air tends to be less dense and
warmer.

Example:
A force exerted by air that is the result of
the weight of air pushing on an area
A measurement of how fast air particles are
moving
Example:
The height above Earth’s surface
Example:
The layer of air that surrounds Earth
Example:
The attractive force between two objects, such
as the force between Earth and you
Example:
Dense, cool air with a high amount of force
Example:
Less dense, warm air with a low amount of
force
Example:
The layer of the atmosphere that contains a high amount
of the gas ozone; it protects Earth by blocking some
ultraviolet (UV) light from reaching the ground.
