The document describes the water cycle through labeling its key processes: 1) Evaporation occurs as the sun causes water to change from a liquid to gas. 2) Transpiration is when plants release water vapor from their leaves. 3) Condensation happens when warm air cools and water vapor condenses into droplets to form clouds. 4) Precipitation results as rain or snow falls from clouds. 5) Runoff and groundwater are how water flows from highlands to lowlands or seeps into the ground.
