The hydrosphere contains all the water found on our planet. Water found on the surface of our planet includes the ocean as well as water from lakes and rivers, streams, and creeks. Water found under the surface of our planet includes water trapped in the soil and groundwater. Water found in our atmosphere includes water vapor. Frozen water on our planet includes ice caps and glaciers. Only about 3% of the water on Earth is “fresh” water, and about 70% of the fresh water is frozen in the form of glacial ice.
