Water Cycle Diagrams
Learn more about where water is on Earth and how it moves using one of the USGS water cycle diagrams. We offer downloadable and interactive versions of the water cycle diagram for elementary students and beyond. Our diagrams are also available in multiple languages. Explore our diagrams below.
The Water Cycle
The water cycle describes where water is on Earth and how it moves. Human water use, land use, and climate change all impact the water cycle. By understanding these impacts, we can work toward using water sustainably.
