What Causes a Cloud to Form
The air in the atmosphere can hold only a certain amount of water vapor, which depends on the temperature and the atmospheric pressure. The more the temperature and the atmospheric pressure, the more the air can hold water vapor. The atmosphere is said to be saturated when a particular air volume has the maximum water vapor it can hold.
Clouds form when:
The air’s moisture has crossed the point of saturation due to evaporation.
The air temperature is cooled to its due point leading to condensation, and thus cannot hold any more water.
They form at a wide range of altitudes. Some are found very close to the ground, while others are high in the atmosphere.
