- TL;DR Summary
- From particles moving in gravitational field view, explain emerging phenomena of air more dense closer to gravitational attraction center.
Could not find reason on molecular level. E.g. here some explanation
"There are two reasons: at higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center."
However, when I start to imagine particles, when there are only a few I get opposite result: as particle moves faster closer to Earth (like a ball bouncing off the floor), it spends less time there, hence average number of particles is less closer to ground. I doubt horizontal speeds make a difference.
Looks to me we have emerging phenomena when number of particles increase over some boundary, the result reverses.
What is that boundary and mechanism that causes such reverse?
