air molecules are very close together stopping moisture from getting in
What is a high pressure system?
100
Troposphere, Stratosphere, Mesosphere, Ionosphere is inside the Thermosphere, and the Exosphere
What are the layers of the atmosphere starting on earth and going up?
100
the water switched syringes which represent high and low pressure systems meeting forming a front resulting in rainy stormy weather and they are they pressure system they are because of the moisture
What happened when you pushed one of the plungers down?
200
the pull or force between earth and the amount of matter in an object
What is the definition of weight?
200
the force that works against compression
What is pressure?
200
Oxygen and Nitrogen
What two gases are most plentiful in the atmosphere?
200
the number of air molecules stay the same they just get closer together
What happens to the air molecules as the plunger is pushed down?
300
yes and when we did the balloon and meter stick experiment it proved that air has weight because when the air was let out of one balloon the balance got uneven proving air has weight and mass
Does air have weight and what did we do in class do prove this?
300
air molecules are far apart allowing moisture to get in
What is a low pressure system?
300
contains shooting stars
The mesosphere contains ____________.
300
A thin layer of oxygen and carbon dioxide located in the stratosphere protecting us from harmful rays of radiation
What is the ozone layer?
400
the amount of matter in an object
What is the definition of mass?
400
a front occurs resulting in rainy and stormy weather
What happens when a high and low pressure system meet and what is the result of the occurance?
400
Exosphere
what layer of the atmosphere are satalights in?
400
in the stratosphere
What do people fly planes?
500
Mass always stays the same and weight can vary from place to place (i.e. space and earth)
What is the biggest difference between mass and weight?
500
it was being compressed by air that had no where to go so it was compressing the cube and this is am example of high and low pressure systems because of the tightness of the molecules
Why did they blue cube shrink and what does it represent?
