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.
For a detailed explanation of where Earth's water is, look at the data table below. Notice how of the world's total water supply of about 332.5 million mi 3 of water, over 96 percent is saline. Of total freshwater, over 68 percent is locked up in ice and glaciers.ven though you may only notice water on the Earth's surface, there is much more freshwater stored in the ground than there is in liquid form on the surface. In fact, some of the water you see flowing in rivers comes from seepage of groundwater into river beds.
