Water vapour is a constituents in air because water vapour rises in the atmosphere & is always present in the atmospere in some or the other quantity.Also 0.0001% of air consist water vapour
NO. Water vapour is created by heating water e.g. when you heat a kettle steam floats out of the top of the kettle, that's water vapour.
If it happens in a cloud, the drops combine until too heavy, and it rains.
You can see water vapour in the air, as when a kettle or pan boils, or when you breathe out into cold air. It depends on the temperature balance between the vapour and the surrounding air.
these form in the sky when water vapour condenses into water droplets

The chemtail from an airplane is the also called a vapour trail when it can be seen. Inside the vapour is all the products of combustion from the engines, thus a "ChemTrail"
Ice crystals of frozen exhaust particles.
All aircraft engines emit hot air and they are usually flying in very cold air, so the hot air appears as a vapour trail.
Clouds are a natural part of the atmosphere, they consist of water vapour, which generally speaking isn't harmful.
The white trail is called a contrail which is short for condensation trail. The fumes that are emitted from the engines of planes contain a large amount of water vapours. When the plane is at a high altitude, the temperature can be low enough to freeze the water vapour into tiny crystals which we see as a white trail. The trail disappears when the water evaporates.
The jet contrails are exaust from the jet engines, which is mostly carbon dioxide and water vapour.
