Hot air rises so does cold air travel downward?

Question

Hot air rises so does cold air travel downward?

Answer 1

Yes. Hot air is less dense than cool air, so hot air rises and cool air falls.

Answer 2

yes.... hot air is lighter than cold air so it rises up and cold sir settles down

Answer 3

Absolutely, cold air is heavier and more dense that hot air!

Answer 4

The simple answer is: Yes.

It's handy to think of it this way. Two air masses of different temperature that 'collide' will not behave in such a nice, neat manner, though.  The air mass 'rolls' around, creating wind, tornados, etc...

Answer 5

Yep!!!! My cousin lives on top of a hill and below him the frost settles on the valley and car windshields while his stay clean

Answer 6

Yes, as said, but not quite that simply. As air flows downward it is compressed adiabatically and gets hotter. Example, the Santa Ana winds of southern CA.

Answer 7

Cold air is more dense so it goes downward.
