Answer:
Water condenses to form clouds.
Explanation:
Water condenses to form clouds-The process of condensation is when water changes to liquid. This can be achieved by either the extreme cooling of air or when the air is saturated with water vapor, that it becomes impossible to hold any more water. When the moist compacts , this brings about an outflow of energy.This energy makes the environment warm up amounting to the multiplicity of air in the atmosphere above. The above explanation results in instability of the atmosphere and cumulonimbus vapors are formed. These vapors aid lightening when its the period of thunderstorm.
