Original answer is INCORRECT. Clouds forming in the sky is a physical change because a chemical change requires a change in the chemical composition of a material and the H2O, no matter a solid liquid or gas, is always H20.

Cloud formation is a physical change, not a chemical change. It involves the process of water vapor condensing into tiny water droplets or ice crystals in the atmosphere to create clouds.
At a frontal boundary, you can typically see cumulonimbus or nimbostratus clouds forming, which bring precipitation such as rain or snow. These clouds often indicate a change in weather patterns as the front passes through an area.
The low puffy white clouds that can change into cumulonimbus clouds are called cumulus clouds. Cumulus clouds are often associated with fair weather, but can grow into cumulonimbus clouds, which are tall, dense, and produce thunderstorms.
Water vapor changes to clouds through the process of condensation. When the air containing water vapor cools and reaches its saturation point, the water vapor condenses onto tiny particles like dust or salt in the air, forming water droplets or ice crystals that make up clouds.
Cirrus clouds typically indicate fair weather, but their presence may signal an approaching change in the weather, such as a front. They are thin and wispy with a feathery appearance, often forming high in the atmosphere.
No, clouds are not nonrenewable. Clouds are continuously forming and dissipating as water evaporates from the Earth's surface, rises into the atmosphere, and then condenses into droplets or ice crystals to create clouds. This cyclical process makes clouds a renewable natural phenomenon.
