Is the atmosphere a heterogeneous or homogeneous mixture?

Answer 1

H3Yit is amixture gas like helium ad hydrogen

Answer 2

I originally thought that the atmosphere was a homogeneous mixture, but then I found out that it's actually heterogeneous for this reason: when you look up into the atmosphere, what do you see? Generally, you see blue, which is the ozone layer (O3) and clouds, which are suspended droplets of water, a separate layer from the other gases. So, the atmosphere is a heterogeneous mixture. However, air on the ground level that is all around you is homogeneous, as you cannot make out the different gases that it composes of.

Answer 3

heterogeneous because of the different elements involved

Answer 4

heterogenous

Answer 5

It can be considered as both.
