The water is not so abundant in the atmosphere and is very variable (o-1 %).
on ancient Earth, nitrogen, water vapor, carbon dioxide, and methane were probably the most abundant gases in the atmosphere.
The water vapor condenses.
The third most abundant gas in the atmosphere is argon.
The % of water vapor is called Humidity. The attached link will give you more information.
Troposphere. This is the lowest section of the earths atmosphere that contains 75% of the earths atmosphere by mass and 99% of the earths water vapour. This section of the atmosphere starts at the surface and extends 7-20km up, the thickness depending largely on where you are in the world.

Cheating for your homework eh? its Gasoline.
Most abundant - Water Vapor
The water vapor condenses.

The Troposhere has the most water vapor then any other layer in the atmosphere.

Evaporation from the ocean
It goes into the atmosphere as part of the water cycle.
About 78% of the atmosphere is nitrogen, while 20% is oxygen. Argon makes up less than 1%. Depending on the location, water vapor would be the third or fourth most abundant, comprising up to 4% of the atmosphere.
