Cloud physics is the study of the physical processes that lead to the formation,
growth and precipitation of atmospheric clouds. Clouds consist of microscopic
droplets of liquid water (warm clouds),...
Water vapor droplets can become cloud droplets when what is reached? ... Water
vapor forming droplets that form clouds directly involves which process?
Clouds will either be composed of ice or water droplets depending on the ... the

Condensation can also produce water droplets on the outside of soda cans or
glasses ... As more water vapor collects in clouds, they can become saturated
Water changes from a liquid to a gas form, called water vapor, through a process
... When the droplets become heavy enough, they fall to the ground as
precipitation. ... Precipitation can take on different forms, but scientists think it
begins with ... Clouds are formed in the air, because when water vapor rises from

There are two ingredients needed for clouds to become visible; water, ...
However, water molecules in the atmosphere are too small to bond together for
the formation of cloud droplets. ... Air can reach the point of saturation in a
