It is difficult to include water vapor in a graph showing the percentages of various gases in the atmosphere because water vapor is highly variable, fluctuating significantly with temperature, humidity, and geographical location. Unlike the more stable gases like nitrogen and oxygen, which make up a constant proportion of the atmosphere, water vapor can range from nearly 0% to about 4% by volume, making it challenging to represent accurately. Additionally, it is a gaseous phase of water that changes with weather conditions, complicating its consistent quantification.
The composition of Jupiter's atmosphere is as follows:Major gases:Molecular hydrogen (H2) - 89.8% (2.0%)Helium (He) - 10.2% (2.0%)Minor Gases (approximately, in ppm):Methane (CH4) - 3000Ammonia (NH3) - 260Hydrogen Deuteride (HD) - 28Ethane (C2H6) - 5.8Water (H2O) - 4
Saturn's atmosphere is primarily composed of hydrogen and helium, with trace amounts of other gases like methane, ammonia, and water vapor. The upper layers are mostly made up of ammonia ice clouds, giving the planet its distinct yellowish color.
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.
The four main gases in Earth's atmosphere are nitrogen (78%), oxygen (21%), argon (0.9%), and carbon dioxide (0.04%). These gases make up the majority of the atmosphere and are essential for supporting life on Earth.
The rare gases, also known as noble gases, make up about 1% of the Earth's atmosphere. This includes gases like helium, neon, argon, krypton, xenon, and radon. These gases are considered rare because they are present in very small concentrations compared to other gases like nitrogen and oxygen.
Nitrogen and oxygen together make up about 99% of the atmosphere by volume. Most of the remaining 1% is argon. Under humid conditions water vapor may make up 2-4% of the air.
78% nitrogen, 21% oxygen, 1% carbon dioxide and other minute gases
Mars has an atmosphere that's at least 95% carbon dioxide.Of the rest, the main ones are nitrogen and argonwhich make up over 4%.
The atmosphere is about 78% nitrogen and 21% oxygen. It's also approx 1% argon, 0.04% carbon dioxide and 1-4% water vapour.
Earth's atmosphere is made up of 78-percent nitrogen, 21-percent oxygen, 0.93-percent argon, and 0.028-percent carbon dioxide. The earth's atmosphere is a very thin layer of these combined gases wrapped around the planet.

Their are 4 ways that gases enter the ocean. Gases can enter the ocean from streams, volcanoes, organisms, and the atmosphere.
In dry air, about 1% is not oxygen or nitrogen. Argon accounts for most of that. However, under extremely humid conditions, water vapor may account for up to about 4% of the atmosphere by volume.
The two main gases are Nitrogen (N2) and Oxygen (O2), which comprise around 78% and 21% of the atmosphere by volume respectively. The remaining 1% is mostly Argon (Ar), followed by Carbon Dioxide (CO2) as well as several other gases present in trace amounts. All of these figures are for dry air, however water vapour (H2O) is also present in air at levels of up to 4%, but this is highly variable depending on localised conditions, and it makes up a lower percentage of the atmosphere as a whole.
