What is the most important difference between cloud droplets and raindrops?

Correct answer: Cloud droplets are small and suspended, while raindrops are larger and able to fall

Correct answer: A. Cloud droplets are usually very small water droplets, or sometimes tiny ice particles, that remain suspended because air currents can support them. They may be present in large numbers without falling to the ground. Through condensation, collision and coalescence, some droplets grow larger and heavier. Once their downward gravitational force is sufficient, they fall as raindrops. Thus the important difference is not the basic substance—both involve water—but their size, mass and ability to fall. Option A is correct because it contrasts suspended small droplets with larger falling drops. Option B is false because cloud droplets are not rock. Option C is false because raindrops are liquid water. Option D is false because droplets change size during cloud development. Memory cue: cloud droplets stay suspended; raindrops are grown, heavier and fall.
