Over long periods of time the concentrations of some gasses such as oxygen and carbon dioxide do change. Water vapor is even more variable, often changing on a daily or hourly basis.
The amounts of gases in the atmosphere are usually expressed as percentages to provide a clear and easily understandable representation of their relative abundance. Percentages allow for a straightforward comparison between different gases, highlighting their proportions in relation to the total atmospheric composition. This method also simplifies the communication of data, making it accessible to a wide audience, from scientists to the general public.
Jupiter's atmosphere is primarily composed of hydrogen (around 75%) and helium (around 24%), with trace amounts of other gases such as methane, ammonia, and water vapor. The exact percentages can vary slightly depending on the specific region of the atmosphere being measured.
As the gases go higher in the atmosphere they start to compose or join together at some point which causes them to change since there is mixture of more than one gas, sometimes they form a different element when certain gases form
Nitrogen ~ 78% Oxygen ~ 21% CO2(and other gasses) ~ 1%
The mesosphere, which is the third layer of the Earth's atmosphere, consists primarily of nitrogen (about 78%) and oxygen (about 21%), similar to the lower layers. However, the concentration of gases in the mesosphere is much lower than in the troposphere, with trace amounts of other gases like carbon dioxide, ozone, and water vapor. The exact percentages can vary slightly due to factors such as altitude and temperature, but nitrogen and oxygen remain the dominant gases.
Showing the amount of gases in the atmosphere as percentages of dry air allows for easy comparison and analysis of the composition of the atmosphere. Since the composition of dry air is relatively stable, expressing the gases as percentages of dry air helps to standardize the data for scientific purposes.
Nitrogen (about 78%) and oxygen (about 21%).
It is simpler because the amount of water vapor in the air can change.

When did people start to change the atmosphere by releasing gases
Showing the amounts of gases in the atmosphere as percentages of dry air allows for easier comparison and understanding of their relative concentrations. It provides a standardized framework that eliminates the variability that water vapor would introduce, making it simpler to analyze and compare the composition of the atmosphere.
Showing gas concentrations as percentages of dry air allows for easier comparison of the relative amounts of different gases in the atmosphere. Dry air is a consistent reference point because its composition is relatively stable, making it a convenient baseline for expressing variations in gas concentrations.
That's because water vapor is so variable in its concentration in the atmosphere.
A pie chart with the percentages of nitrogen, oxygen, and other gases in the Earth's atmosphere typically shows nitrogen at around 78%, oxygen at roughly 21%, and other gases like argon, carbon dioxide, and neon making up the remaining 1%. Each segment of the pie chart represents the proportionate amount of each gas in the atmosphere.
The atmosphere of the earth is the layers of air that surround the Earth. They contain nitrogen, oxygen, carbon dioxide, water vapor, and small percentages of other gases.
A pie chart is often the best type of graph to show percentages.
