How does the composition gases changes as you travel in earths atmosphere?

As you travel higher in Earth's atmosphere, the composition of gases changes in terms of their concentration. Oxygen, nitrogen, and argon are the most abundant gases in the lower atmosphere, while the percentage of oxygen decreases and other gases like helium and hydrogen become more prevalent in the upper atmosphere. The overall pressure also decreases with altitude, causing the air to become less dense.


Why is the percentage of argon in the earths atmosphere today the same as it was in the earths early atmosphere?

Argon is a noble gas and does not react with other elements in the atmosphere, so it has remained relatively constant over time. The initial percentage of argon in the Earth's atmosphere was likely determined by the gases present during the planet's formation. The lack of significant processes that remove or add argon to the atmosphere has helped to maintain its percentage over time.


What percentage of the suns radiation that reaches the earths atmosphere is absorbed by earths surface?

About 50% of the sun's radiation that reaches Earth's atmosphere is absorbed by the Earth's surface. The remaining energy is either reflected back to space or absorbed by the atmosphere.
