How do clouds form?from climatekids.nasa.gov
These two processes are how clouds form. Condensation happens with the help of tiny particles floating around in the air, such as dust, salt crystals from sea spray, bacteria or even ash from volcanoes . Those particles provide surfaces on which water vapor can change into liquid droplets or ice crystals. A large accumulation of such droplets ...
What are clouds made of?from climatekids.nasa.gov
Clouds are made up of a bunch of cloud droplets bundled together with raindrops. Image credit: NASA/JPL-Caltech/Alex Novati. We usually think of clouds as being up in the sky, but when conditions are right, a cloud can form at ground level, too. Then it’s called “fog.”.
What is a large accumulation of droplets or ice crystals?from climatekids.nasa.gov
A large accumulation of such droplets or ice crystals is a cloud. Dust and other particles floating in the air provide surfaces for water vapor to turn into water drops or ice crystals. The tiny drops of water condense on the particles to form cloud droplets.
