Discusses how water forms, how to keep it clean, and its importance to humans and the ecology. All life on Earth depends on the water cycle! The Water Cycle is a fascinating book that introduces children to this important cycle using a clear, step-by-step approach. Kids will learn about how different processes, including evaporation, condensation, precipitation, and run-off, work together to move water from the ground to the air and then back down again. Full-color diagrams and beautiful images accompany clear text to help make the water cycle come alive for kids as they learn: How plants contribute to the water cycle through transpiration; How water trapped underground for thousands of years remains part of the water cycle; The importance of water to all living things; Ways in which people can help protect Earth's water and keep it clean.
