      When warm air rises, it expands and cools. Cool air can’t hold as much water vapour as warm air can, so some of the vapour condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle. When billions of these droplets come together they become a visible cloud.

      A cloud is a large group of tiny water droplets that we can see in the air.

      Clouds are formed when water on Earth evaporates into the sky and condenses high up in the cooler air.

      In atmosphere, tiny droplets of water or ice crystals settles on dust particles to form clouds. These droplets are so small , approximately 100th of millimetre.

      Clouds will either be composed of ice or water droplets depending on the height of the cloud and the temperature of the atmosphere. Because the droplets are so small, they can remain in liquid form in temperatures as low as -30 °C. Extremely high clouds at temperatures below -30 °C are composed of ice crystals.
