Answer: Waterfalls from the atmosphere as rain, ice, or snow. (Option A)
The water cycle has three phases’ evaporation, condensation and precipitation
Sun is causing the water to evaporate in the form of water vapors
As the water vapor reaches the atmosphere (clouds) the water vapor join to change into water this process is called condensation.
In the atmosphere, the water vapors combine to form large water droplets (rain).Therefore, when the water droplets become larger and heavier they fall down due to gravity and this process is called precipitation. So the raining process is called precipitation
And the water running down from the mountain is called a run-off
