Which conditions are necessary for clouds to form?

O warming air and relative humidity

O cooling air and high humidity

O cooling air and surfaces for condensation

O warming air and surfaces for condensation

L

Cool air and surfaces for condensation

Answer: Option C

Explanation:

The formation of the clouds basically depends on certain factors. These factors are moisture, cooling air and condensation surface.

There must be enough water vapor in the atmosphere to form cloud. The temperature must be cool enough to allow condensation. There be cooling air present in the atmosphere.

Then some tiny particle of aerosols and dust is required in order to provide surface for the cloud formation to take place.
