How are clouds formed?
When the sun shines over rivers, lakes and oceans of the world it heats up the surface of the water. The water turns into gaseous water vapour on being heated and begins to rise into the air. As it goes higher, the water vapour begins to cool down and turns back into water droplets. The temperature at which water condenses is called the dew point. The dew point is not a constant because it depends on the amount of water present in the air.
These water droplets in clouds are so tiny that they hang suspended high up in the earth’s atmosphere. Over a period of time condensed water vapour accumulates to form clouds. The water droplets higher up in the cloud are colder than the droplets below to the extent that some parts of a cloud can even contain small bits of ice. After a while the cloud becomes heavy with water .please upvote
droplets and gravity brings the water droplets back down as rain.
Clouds form from water in the sky. The water may evaporate from the ground or move from other areas. Water vapor is always in the sky in some amount but is invisible. Clouds form when an area of air becomes cooler until the water vapor there condenses to liquid form. At that point, the air is said to be "saturated" with water vapor. The air where the cloud forms must be cool enough for the water vapor to condense. The water will condense around things like dust, ice or sea salt - all known as condensation nuclei. The temperature, wind and other conditions where a cloud forms determine what type of cloud it will be.
