Clouds are born from the water cycle. The sun heats water in oceans, lakes, and rivers, turning it into invisible water vapor. This vapor rises, expands, and cools. Once it cools enough, it condenses into tiny liquid water droplets or ice crystals around microscopic airborne particles like dust or pollen, forming a cloud.The entire lifecycle of a cloud can be broken down into three simple steps:1. EvaporationThe sun warms up bodies of water on the Earth's surface. This thermal energy causes liquid water to evaporate, transforming into an invisible, lightweight gas known as water vapor. As the vapor heats up, it begins to rise into the atmosphere.2. Cooling and ExpansionAs the invisible water vapor rises higher into the sky, the atmospheric pressure drops. This decrease in pressure allows the rising air mass to expand. When gases expand, they naturally lose heat, causing the temperature of the air to drop.3. CondensationWhen the rising air cools to its "dew point" (the temperature at which the air is completely saturated with moisture), it can no longer hold the water as an invisible gas. The vapor condenses back into visible, microscopic liquid water droplets or ice crystals. To do this, the moisture needs a surface to cling to, so it attaches to microscopic floating aerosols like dust, salt, ash, or pollen, known as cloud condensation nuclei. Billions of these tiny floating droplets bundle together to form a visible cloud.For a quick, visual breakdown of exactly how rising moisture turns into the fluffy white clouds we see in the sky
