Water vapor enters the air as water at the surface evaporates or as plants transpire water vapor from their leaves.
The Earth grew by countless impacts from rock and dust in the early Solar System. This rock and dust contained ice which turned to vapor (steam) when it struck the Earth. This vapor was forced to the surface in much the same way that sediment settles in a glass of muddy water. Over time the crust of the Earth cooled and eventually the vapor condensed into the liquid water that we drink.
The water on plants and objects is "dew." It is caused by the condensation of water vapor on surfaces that have cooled by radiating their heat. The air that cools overnight can no longer hold as much moisture, and will deposit water drops on any sufficiently cool surface.
Water on the surface of the moon will rapidly turn to water vapor as there is no atmospheric pressure on the moon. The vapor will then escape the moon's gravity which is much weaker than the gravity on Earth.
== == Very simply, a cloud is "FOG" that is above the Earth's surface, rather than in contact with the ground.Clouds and fog are one and the same thing, very tiny droplets of condensed water vapor, so small that they do not have enough weight to fall to the Earth, and consequently they just float around in the air. IF and when enough of these droplets of condensed water vapor, collide and stick together, they become heavy enough for gravity to cause them to fall to Earth, and that is what we call rain. Other forms of precipitation occur when the vapor (or rain) is exposed to colder temperatures. === ===Clouds are formed when water vapour in the air is cooled and condenses as part of the water cycle. Clouds consist of billions of tiny water droplets (and even ice crystals) floating in the sky and appear in a variety of shapes and sizes depending on how and where they formed.I found this answer at http://www.rcn27.dial.pipex.com/cloudsrus/clouds.HTMLHope this helps.

Condensed water vapor near the surface is referred to as precipitation. The condensed water vapor forms clouds and allows the water to return to the surface as rain, ice, sleet, or snow.
It condensed water vapor to form the oceans by the Earth's vapor into the water.
Fog, mist.
Condensation
Rain: The condensed water vapor that first evaporated from the earths surface (see water cycle)
There are a number of names for condensed water vapor in the atmosphere: Mist, fog, clouds, rain, sleet, snow, hail are names for some of the types of condensed water vapor.
Condensed Water Vapor
clouds
water condenses and when there is enough water vapor is condensed it rains so it may transpire or evaporate once more
When we boil water and expose the steam (water vapor) to a cold surface, it will condense into tiny drops of water on the cold surface. If you can see the 'steam'rising above the water, it has already condensed into tiny droplets of water in the cool air.
