The atmosphere is rotating at approximately 1 rotation/day at every altitude. It might be rotating a bit slower than that as altitude increases, but I'm no expert. To calculate speed based on that, use the formula for calculating speed from angular velocity. Here are some numbers for your diagrams.
altitude (km) -> speed relative to a non-rotating earth (km/h)
0 -> 1667
20 -> 1673
50 -> 1681
85 -> 1690
690 -> 1848
10000 -> 4285 ? (This one is practically in space, I doubt it is rotating at exactly the same rate.)
In your diagram for diffusion, simply draw some arrows pointing towards the center of the earth and label them "gravity". Gravity cancels out the diffusion.
In your flat-earth diffusion diagram, the water is preventing the atmosphere from diffusing? This doesn't make sense. When water touches a vacuum, it turns into a gas, and diffuses away just like the atmosphere.
So ask yourself why do you choose a model RE as vague, contradictory, in any case do not apply instead of FE model logical, understandable and applicable in all situations
Just because you don't understand it doesn't mean it is contradictory.
Look to the answers: "There is no horizontal force so why the atmospher is moving?" The answer they said me: "Because of friction".
"What happens on the outside of the atmospher". "There is no friction on atm".
"How atmospher is continuesly moving with us as same speed with no difference?" "because there is friction"
Then "Why atm don't difuzes the space?" ... "blabla..."
"Is every altitude the friction and gravity same, so how atmospher has same speed on everywhere" "The speed is different" >> Then draw a "velocity (speed)" diagram.
1. There is no friction between the atmosphere and space. Space is made of nothing. You can't have friction between something and nothing.
2. There IS friction between the atmosphere and the ground, if the air is moving relative to the ground.
3. If the atmosphere is moving faster than 1 rotation/day, then friction causes it to slow down.
4. If the atmosphere is moving slower than 1 rotation/day, then friction causes it to speed up.
5. If the atmosphere is moving at exactly 1 rotation/day, then there is no friction.
6. Gravity prevents the atmosphere from diffusing into space. This has nothing to do with friction.
