Clouds are everywhere! When it gets really cold and you can see your breath, that’s a little cloud.
When water boils and steam rises off it, that’s a cloud, too. When the fog rolls in, you guessed it—it’s a cloud.
The air around us is filled with moisture. Air soaks up water from oceans, lakes, and rivers. As air rises from the warmth of the ground and meets cooler air above, its temperature falls. This causes the moisture to form microscopic droplets of water. That process is called condensation. Clouds are made up of millions of tiny droplets.
