In this media gallery of satellite images captured by NASA and ground images captured by NASA and the U.S. Geological Survey (USGS), students are introduced to different views and various scale sizes of Earth as they observe where water is found on our planet. Water covers 75 percent of Earth’s surface, and almost all of it is found in oceans that wrap around the planet. The remaining water is found in freshwater resources, such as precipitation, lakes, rivers, groundwater, and sea ice. In this gallery, students can explore where Earth’s water is found and that it exists in liquid water and solid ice forms across the planet.
