When water vapor in the atmosphere cools, it may form a) wind. b) a gas c) steam. d) a cloud

Answer: Option D a cloud

Explanation:

The process of cooling of the water vapour in the atmosphere is termed as condensation.When the water vapour condenses it combines with other dust and particulate matter present in the atmosphere. When this happens tiny droplets are formed. Slowly, these tiny droplets combine together and form bigger structures which are known as clouds.The cooler the temperature in the atmosphere the faster the process of formation of clouds is.When the clouds become too heavy precipitation takes place, and the water falls back on earth in the form of rain.This rainwater is collected in several water bodies and as groundwater.In the presence of the sun, the water again gets heated up and forms water vapour and this process is called as evaporation.The water vapour again cools down and condenses on reaching the atmosphere and the cycle continues. This cycle is known as water cycle.
