Exploring the Formation and Composition of Clouds

The video explains how clouds form, starting with the sun warming the ground, causing air to rise and cool. Water vapor condenses on tiny particles called condensation nuclei, forming cloud droplets. These droplets are numerous and light, allowing them to float as clouds. When droplets combine and grow heavy, they fall as rain.
