What is the order of the layers of the atmosphere, top to bottom
1) Troposphere 2) Stratosphere 3) Mesosphere 4) Thermosphere
When the Earth moves around the sun, this is called...
revolution
What is important about the stratosphere
It contains ozone nad absorbs ultraviolet light
What is the layer of the atmosphere that is divided into two layers
Thermosphere
What are the names of each of these layers
Ionosphere and Exosphere
What is important about the troposphere
It contains the most air molecules (this is the layer we live in)
Why is the mesosphere important
It burns up meteoroids and prevents most from damaging earth
What are three reasons our atmosphere is important
1) It regulates temperature so that water stays in liquid form 2) It protects us from radiation 3) It holds gases needed for life: oxygen, nitrogen, carbon dioxide, etc.
How do we know air has mass
When you weigh a balloon without air and then blow it up and weigh it again, it weighs more. Air also has molecules as well as particles of dust and liquid and these things have mass
How does a suction cup stay on a smooth surface
When you press it down, you force the air out, and it is "sealed" to the surface and creates a partial vacuum. Therefore the air on top pushes it down and there is no air inside to push it up
