Question

What is the reason that rainfall occurs in drops and not as a continuous stream?

• A. The air resistance of the atmosphere.
• B. The dust particles in the atmosphere.
• C. The oxygen in the atmosphere.
• D. The water vapour in the dry air.

Answer 1

The correct option is B The dust particles in the atmosphere.

The water vapours present in the clouds are condensed on the individually isolated dust particles present in the air. When the weight of these dust particles and water droplets collectively overcomes the upward air convection, they fall downwards in form of individual droplets.
