Why is the mesosphere important

Back 56

It burns up meteoroids and prevents most from damaging earth

Front 57

What are three reasons our atmosphere is important

Back 57

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.

Front 58

How do we know air has mass

Back 58

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

Front 59

How does a suction cup stay on a smooth surface

Back 59

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
