0% (at -44 degrees F) to 4% (at 86 degrees F). It's produced from the evaporation of liquid water, and is invisible. Almost all of it is contained in the troposphere. It's the condensation of water vapor that forms clouds, rain, snow, and other precipitation.
The percentage of water vapor found in the air is actually not steady. The amount of water vapor differs depending on the temperature and density of air and the location from where it is measured. Like in the desert, it is possible to be only 0% while in a jungle it could go up to 90%.
The percentage of water in the atmosphere is 0.001%.
Water vapor accounts for between 40 - 50% of the earth's atmosphere.

The water vapor condenses.
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.
It goes into the atmosphere as part of the water cycle.
The water is not so abundant in the atmosphere and is very variable (o-1 %).

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