Thermal energy causes some of the molecules at the outer edge of the Earth's atmosphere have their velocity increased to the point where they can escape from the planets gravity. T;)

What kind of gas is most affected by thermal escape?

Light gases; Gases that are light weight will more easily reach escape velocity than heavier gases.


Which layer do light gases escape earths gravity?

Earth's lighter gases such as Hydrogen and Helium will rise to the top of the atmosphere. Since they are very light, they will easily be knocked awry by the solar wind, the stream of charged particles coming from the Sun.


Can helium gas spread?

Yes, like most gasses it can spread within currents and mix in with other gases. It is lighter than air, so on earth it will rise above the heavier gases of nitrogen and oxygen that make up our atmosphere. It does appear in the earths atmosphere in trace quantities, but the majority will escape earths gravitation pull and dissipate into space.
