Transcript of Water exists on earth in three states: solid (ice, snow), li Water exists on earth in three states: solid (ice, snow), liquid and gas (water vapor). Oceans, rivers, clouds and rain are constantly changing: the surface water evaporates, cloud water precipitates, rainfall seeps into the ground, etc.. However, the total amount of water does not change the planet. The circulation and conservation of water on Earth is called the hydrologic cycle, or water cycle.
The worldâs water exists naturally in different forms and locations: in the air, on the surface, below the ground and in the oceans. Just 2.5% of the Earthâs water is freshwater, and most is frozen in glaciers and ice sheets. About 96% of all liquid freshwater can be found underground. The remaining small fraction is on the surface or in the air.
