Clouds are made of tiny water droplets or ice crystals, which are liquids and solids, respectively. These droplets and crystals are suspended in the air, forming the visible cloud we see.

While clouds are formed from water vapor, which is a gas, the water vapor condenses into tiny liquid droplets or freezes into ice crystals as it rises and cools in the atmosphere.

So, to answer your question: clouds are made of liquids (water droplets) and solids (ice crystals), but they are formed from a gas (water vapor).
