This medium-2 worksheet shifts focus toward where water lives and how it changes form across the planet. Part A offers nine fill-in-the-blank prompts about the sun's energy, sunny-day evaporation, and the cooling process that creates tiny droplets in the sky. Part B is a matching exercise pairing four real-world locations—sky, falling, ocean, and underground—with the corresponding form water takes there, including groundwater, saltwater, precipitation, and water vapor or droplets.
