Rain and drizzle are both liquid precipitation so on what basis are they differentiated?

Correct answer: On the basis of drop size and falling intensity

Correct answer: A. Rain and drizzle are both forms of liquid precipitation, so both contain liquid water. They are mainly distinguished by the size of their drops and by how they fall. Drizzle consists of very small, fine droplets that usually fall gently and may remain suspended or drift easily in light air movement. Rain has comparatively larger drops and generally reaches the ground with greater falling intensity. Option A is correct because it identifies the observable physical difference. Option B is wrong because drizzle is made of water. Option C is wrong because ordinary rain is liquid, not always solid; snow and hail are solid forms. Option D is wrong because rain and drizzle are atmospheric water processes, not rock processes. Memory cue: small, gentle liquid drops mean drizzle; larger, stronger-falling drops mean rain.
