78% nitrogen, 21% oxygen, 1% carbon dioxide and other minute gases
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.
argon
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.

Yes, water vapor is one of the most abundant gases in Earth's atmosphere. It varies in concentration depending on location and weather conditions, but it typically makes up around 1-4% of the atmosphere by volume.
Their are 4 ways that gases enter the ocean. Gases can enter the ocean from streams, volcanoes, organisms, and the atmosphere.

It was about 4 billion years ago, that the Earths oceans formed
The four most abundant gases in Earth's atmosphere are nitrogen, oxygen, argon, and carbon dioxide. Nitrogen makes up about 78% of the atmosphere, oxygen around 21%, argon about 0.9%, and carbon dioxide less than 0.04%.
