Rain

Rain

Rain is water that falls from the sky in drops. When the drops are very small it is called drizzle. [AM] {GC} {WW}
Rain is formed by a process called coalescence. The clouds are made up of millions of minute droplets of water and as these droplets collide, they join together, forming larger droplets. Gradually, the droplets increase in size until they are too heavy to be kept up in the cloud by air currents and fall as raindrops. [VH] {WC}
