The hydrosphere is the total amount of water on a planet, which moves through the hydrosphere in the water cycle. Hydrospheres include water on the surface of the water, underground, and air, and the Earth's hydrosphere is made up of oceans, lakes and rivers, glaciers, ice caps, and icebergs. The hydrosphere covers all the water present on the Earth's surface. Some of the major importance of the hydrosphere is that water maintains various life forms and plays an important role in ecosystems and regulates the atmosphere. The activities of modern humans have a tremendous impact on the hydrosphere. For example, water splitting, human development, and pollution all affect hydrosphere and natural processes.
