Final answer:
Clouds are the visible aggregates of minute water droplets or tiny ice crystals suspended in the air, forming through the condensation of water vapor carried by rising air currents in the atmosphere.
Step-by-step explanation:
The visible aggregates of minute water droplets or tiny ice crystals suspended in the air are known as clouds. These droplets or ice crystals form when water vapor in the atmosphere cools and condenses. This condensation occurs when rising air currents carry water vapor higher into the atmosphere where it cools down.
If these water particles grow large enough, they can fall to the ground as various forms of precipitation such as rain, snow, sleet, or hail. Unlike clouds, fog is a type of cloud that forms close to the ground, and therefore it is not the correct answer in this context. Rain and snow are forms of precipitation that result when water droplets or ice crystals in clouds become heavy enough to fall to the earth's surface.
