Identify the stages of the water cycle in this model

 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

the dark variety, as they are not visible on the dark tree barks

explanation:

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
