Clouds are created when water vapor, an invisible gas, turns right into liquid water droplets. This water droplets type on small particles, like dust, that are floating in the air.

You cave up a wet bath towel and, when you come back, that dry. You set out a key of water for your dog and also when friend look again, the water level in the bowl has dropped even though Woofy has actually been nowhere near the bowl.

You are watching: What two conditions are required for cloud formation

Where walk the missing water go? that evaporated. That way some the the liquid water in the towel or bowl changed into one invisible gas dubbed water vapor and also drifted away into the atmosphere. (Notice the “evaporated” has the word “vapor.”)

The very same thing is continuous happening with oceans, lakes, rivers, swamps, swim pools – and everywhere water is in contact with air.

Liquid water alters into a gas once water molecules acquire extra power from a heat resource such as the sunlight or from other water molecules running right into them. This energetic molecules then escape native the fluid water in the type of gas. In the procedure of an altering from liquid to gas, the molecules absorb heat, i m sorry they bring with them into the atmosphere. That cools the water they leaving behind.

This process is called evaporation and also it"s the begin of just how clouds space formed. Photo credit: yellowcomic.com/JPL-Caltech/Alex Novati


The air have the right to only hold a certain amount of water vapor, depending on the temperature and also weight of the wait – or atmospheric press – in a offered area. The greater the temperature or atmospheric pressure, the much more water vapor the air deserve to hold. Once a particular volume of air is holding all the water vapor it deserve to hold, that is claimed to be “saturated.”

What happens if a saturated volume of air cools or the atmospheric pressure drops? The wait is no much longer able to host all the water vapor. The overfill amount transforms from a gas into a liquid or hard (ice). The process of water an altering from a gas to a fluid is dubbed "condensation," and also when gas alters directly into a solid, the is called "deposition." these two processes are exactly how clouds form.

Condensation happens with the aid of small particles floating around in the air, such together dust, salt crystals from sea spray, bacteria or also ash indigenous volcanoes. Those particles administer surfaces on i beg your pardon water vapor can change into liquid droplets or ice cream crystals.

A large accumulation of such droplets or ice crystals is a cloud.

Dust and other corpuscle floating in the air administer surfaces for water vapor to turn right into water autumn or ice cream crystals. The tiny drops the water condensation on the particles to kind cloud droplets. Clouds are made up of a bunch that cloud droplets bundled together with raindrops.

We generally think that clouds together being up in the sky, yet when conditions are right, a cloud can type at floor level, too. Then it’s dubbed “fog.” If you’ve ever before walked through fog, did you do it walked v a cloud.

Although the basic idea the cloud development is easy to understand, there is much an ext to learn. Peek beneath a cloud’s fluffy exterior, and also you’ll uncover a people of complexity. In fact, clouds are considered one of the most an overwhelming aspects that climate science.

That’s because truly expertise clouds needs a deep expertise of the entire atmosphere. Researchers are working to increase their understanding, v the aid of tools such as those on yellowcomic.com’s Terra, Aqua, Aura, CALIPSO, CloudSat and other satellites that observe different aspects of clouds.

The much better we have the right to understand clouds and also the setting that creates them, the better we can find out what’s happening come our climate.
