The percentage of water vapor in the atmosphere varies significantly depending on location and weather conditions, typically ranging from about 0% to 4% by volume. In warm, humid areas, it can reach higher levels, while in cold or dry regions, the concentration is much lower. Overall, water vapor is a crucial component of the Earth's atmosphere, playing a key role in weather and climate.
0 to 4 percent
When you see a list of the components of air, they refer to DRY air, because the amount of water vapor varies. If the relative humidity is 100% and the temperature is 104F, water vapor would make up 7% of that air. I doubt the dew point has ever hit 104F, so almost certainly it's never been that high and is usually a good bit less. When temperatures drop well into the double digits below 0, there is only a barely-detectable amount of water vapor. So those component lists floating around describes dry air, or the make-up of the air that isn't water vapor. Those numbers are fairly constant whereas if you tried to include water vapor, you couldn't come up with hard numbers because they are all displaced by any water vapor in proportion to how much of the dry air they make up.
Carbon dioxide (CO2) makes up about 0.04 percent of the Earth's atmosphere, not four percent. The gas that constitutes around four percent of the atmosphere is water vapor, although its concentration can vary significantly based on temperature and humidity. Water vapor plays a crucial role in weather and climate processes.
The amount of water vapor in the air varies considerably depending on climate and weather. In a desert water vapor may account for a tiny fraction of a percent of the air. In a tropical rainforest during a storm water vapor may account for as much as 4% of the air.
When water vapor changes into tiny drops of water, it is called condensation. This process occurs when the air cools down and cannot hold as much moisture, leading the water vapor to transform into liquid water droplets.

90 percent of water vapor evaporate from bodies of water.
If the relative humidity is 50 percent, the air is holding half of the maximum amount of water vapor it can hold at that temperature. This means the air is holding 50 percent of the water vapor it could potentially hold.
The troposphere is the layer of the atmosphere that contains around 99 percent of the water vapor. This is the layer closest to the Earth's surface and where most weather phenomena occur due to the presence of this water vapor.

No, it is always less than one hundred percent.
Oceans and lakes are the main sources of water vapor in the Earth's atmosphere. The process of evaporation occurs when water changes from liquid to vapor due to heat from the sun, accounting for approximately 90 percent of the Earth's water vapor.
water vapor
Water vapors makes up only a few percent of the mass of the atmosphere. However, this small amount of water vapor has in oceans and water bodies changes to a gas, water vapor. The mount of water vapor in the air is called humidity
Ninety six percent of all Earth's water is in the oceans. The rest of Earths' water comes from lakes, rivers, and from vapor in the air.
Dust, water vapor etc are in troposphere. It is the closest layer.
