If updrafts are very strong why can the fall of precipitation particles be delayed?

Answer and explanation

Correct answer: Upward air can hold particles in the cloud longer

Correct answer: A. Precipitation particles are pulled downward by gravity, but an updraft is a rising current of air. If the upward air movement is strong, it can oppose the particles’ downward fall and keep them suspended inside the cloud for longer. During this extra time, droplets or ice particles may collide, grow, freeze, or melt before eventually becoming heavy enough to fall. B is incorrect because an updraft does not remove or switch off gravity; it only produces an upward force or air movement. C is incorrect because precipitation particles contain water in liquid or solid form. D is incorrect because an updraft does not turn a cloud into rock. Memory cue: strong updraft means longer cloud residence time, not zero gravity.
