How are thunder head clouds formed?

Thunderhead clouds, or cumulonimbus clouds, are formed through the rapid upward movement of warm, moist air, which cools and condenses as it rises. This process is often triggered by convection, where the sun heats the Earth's surface, causing the air above it to warm and rise. As the air ascends, it cools, leading to the formation of water droplets or ice crystals, creating the towering structure of the thunderhead. These clouds are associated with thunderstorms, heavy rain, and severe weather phenomena.
