Air is Matter
This term describes anything that has mass and takes up space
matter
When you push a syringe plunger down, you do this to the air, packing the particles into a smaller space
Compress
This is the layer of the atmosphere closest to Earth where all our weather happens
Troposphere
This is a scientist who studies and predicts the weather
meteorologist
Air always flows from areas of high pressure toward areas of this.
Low pressure
This is the specific amount of "stuff" or matter in an object, often measured in grams.
mass
In the jar-and-bottle system, squeezing the jar causes the water in the straw to do this
Go up
As a weather balloon travels higher in altitude the air pressure around it does this
decreases
This weather factor is the amount of water vapor in the air.
Humidity
This is the term for air that is actively moving from one place to another.
wind
To prove air has mass, a student should weigh a balloon before and after doing this to it
inflating (expanding) or blowing it up
When air is compressed in a syringe, the particles do not change size, but they do move much closer to each other. This causes the air pressure to do what?
Increase
This is the height of an object, like a balloon or a mountain, above the ground(sea level)
altitude
The study of weather is called
meteorology
On a weather map, these lines connect locations that have the same air pressure
Isobars
Air is not just "empty space"; it is actually a mixture of these.
gases
This weather tool is used by meteorologists to measure the pressure of the atmosphere
Barometer
This layer sits above the troposphere and contains the protective ozone layer
stratosphere
Wind is created when air moves from _______ pressure to _______ pressure
High to Low
What causes a bag of chips to expand as you go up a mountain
The air pressure inside the bag becomes higher than outside the bag
If you trap air in a syringe and push the plunger, the air stays inside because it is made of these tiny pieces that are too small to see.
particles
When particles collide with each other or their container it causes this.
What is air pressure
Why does warm air rise?
It is less dense than cooler air
Name at least 3 weather factors
temperature, humidity, air pressure, precipitation, wind speed/direction
This form of energy comes from heat and can cause particles to move faster and spread out.
thermal energy
