The correct answer is evaporation, condensation, precipitation. This is the correct sequence of events in the water cycle. Evaporation occurs when water changes from liquid to vapor and rises into the atmosphere. Condensation happens when the water vapor cools and forms clouds. Finally, precipitation occurs when the water droplets in the clouds become heavy and fall to the ground as rain, snow, sleet, or hail. This process is essential for the continuous circulation of water on Earth.
