Water vapor is totally invisible. If you see a cloud, fog, or mist, these are all liquid water, not water vapor.

Water vapor is extremely important to the weather and climate. Without it, there would be no clouds or rain or snow, since all of these require water vapor in order to form. All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow.

When liquid water is evaporated to form water vapor, heat is absorbed. This helps to cool the surface of the Earth. This "latent heat of condensation" is released again when the water vapor condenses to form cloud water. This source of heat helps drive the updrafts in clouds and precipitation systems, which then causes even more water vapor to condense into cloud, and more cloud water and ice to form precipitation.

No, rain is not condensation. Rain forms when water vapor in the atmosphere condenses into water droplets that become heavy enough to fall to the ground. Condensation is the process by which water vapor turns into liquid water or ice.

What is the transformation from water vapor turns to rain?

The transformation from water vapor to rain is called condensation. This occurs when water vapor in the atmosphere cools and changes back into liquid form, forming clouds. When the water droplets in the clouds become too heavy to remain suspended, they fall to the ground as rain.
