Question

Which of the following plays a direct role in the formation of rain droplets?

• A. Filtration
• B. Precipitation
• C. Humidity
• D. Transpiration

Answer 1

The correct option is B

Precipitation

Water vapour along with hot air rise high in the atmosphere. As the air rises, it expands and cools. This cooling causes the water vapour to condense and form droplets. The process of conversion of water vapor into water by cooling is called as condensation. These droplets grow in size and fall down in the form of rain by the process of precipitation.
