Water Vapor enters the air by something called "evaporation process". Water evaporates from bodies of water and such and transpiration is the water vapor that plants give off, so to describe the full process of how water vapor enters the air, they combine both and get the term evaporation process !

Answ2. Air has only a limited capacity to carry water vapour, this capacity diminishes as the air gets colder. When this happens, the water vapour will condense out, at first as a fine mist, but eventually as water droplets. Or hail or snow.

Whenever a water molecule leaves a surface and diffuses into a surrounding gas, it is said to have evaporated. Each individual water molecule which transitions between a more associated (liquid) and a less associated (vapor/gas) state does so through the absorption or release of kinetic energy. The aggregate measurement of this kinetic energy transfer is defined as thermal energy and occurs only when there is differential in the temperature of the water molecules. Liquid water that becomes water vapor takes a parcel of heat with it, in a process called evaporate cooling. The amount of water vapor in the air determines how fast each molecule will return back to the surface. When a net evaporation occurs, the body of water will undergo a net cooling directly related to the loss of water.
In the US, the National Weather Service measures the actual rate of evaporation from a standardized "pan" open water surface outdoors, at various locations nationwide. Others do likewise around the world. The US data is collected and compiled into an annual evaporation map. The measurements range from under 30 to over 120 inches per year. Formulas can be used for calculating the rate of evaporation from a water surface such as a swimming pool. In some countries, the evaporation rate far exceeds the precipitation rate.
To put it simple the heat from the sun on the surface of the water causes the water to go up as water vapor.
Water vapor gets into the air through evaporation during the water cycle. The water then condenses and falls back to the earth in the form of rain or snow.
through the process of evaporation, sublimation, and transpiration. Mrs. lull taught me that unless it's wrong.
By the process of evaporation
it vapor when the weather is wet and if your driving you can see it on your windshield
Water vapor in the air is practically the same as measuring the humidity that is in the air.
It means how much water vapor is suspended in the air, or how humid it is.
Water vapor and air. Water vapor condenses to produce clouds. Even if air has no visible clouds it still has water vapor.
Humidity is caused by water vapor in the air, but rain contributes to the amount of vapor in the air, so I suppose you could say they both do, but it's the water vapor that truly creates humidity.
water vapor in surrounding air condenses on the cold surface
Water vapor in the air is water in the form of a gas.
Water vapor enters the air as water at the surface evaporates or as plants transpire water vapor from their leaves.

The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.

It takes a lot of energy to turn water into water vapor. The amount of energy that the water gains to turn into water vapor begins to be transferred into the surrounding air. If the air is willing to take on more energy the water vapor condenses quicker. This is why hot air will hold more water vapor than cold air.

Saturated air is more dense.

Its ratio of the air's water vapor content to its water vapor capacity :)
