Final answer:
The water cycle involves evaporation, condensation, and precipitation.
Step-by-step explanation:
The water cycle is a continuous process that involves the movement of water on, above, and below Earth's surface. At point A in the diagram, the process taking place is evaporation. This is when water changes from a liquid state to a gaseous state and rises into the atmosphere. At point B, the process shown is condensation. This is when water vapor in the atmosphere cools and forms water droplets, which then come together to form clouds. Finally, at point C, the process depicted is precipitation. This is when water droplets in the clouds combine and become heavy enough to fall back to Earth as rain, snow, sleet, or hail.
