What must occur before clouds can form?
Answer (3)
The water vapor must lose heat energy
The** three conditions** that must occur before clouds can form Sufficient water vapor must be present in the air. Water vapor is the invisible gas form of water. It is all around us, even in dry air.
What are the other conditions?
A surface for water vapor t o condense on is needed. This is called a cloud condensation nuclei (CCN). CCN can be anything from dust particles to salt crystals.
The air must cool to its** dew point.** The dew point is the temperature at which the air is saturated with water vapor. When the air reaches its dew point, the water vapor will condense on CCN and form clouds.
In addition to these three conditions, there are other factors that can affect cloud formation, such as the wind and the amount of sunlight.

Clouds form when there is sufficient water vapor in the air, condensation nuclei available for the vapor to condense upon, and the air cools to its dew point. When these conditions are met, the water vapor condenses into tiny droplets, creating clouds. This process usually occurs as warm, moist air rises and cools, allowing for condensation to take place.
