Only 3% of the Earth's water is fresh water. Most of it is in icecaps and glaciers (69%) and groundwater (30%), while all lakes, rivers and swamps combined only account for a small fraction (0.3%) of the Earth's total freshwater reserves. Water resources are sources of water that are potentially useful.
About 71% of the Earth's surface is covered with water, most of which is found in the oceans. In fact, 97% of Earth's water, nearly all of it, is in the Earth's oceans. This means that just 3% of Earth's water is fresh water, water with low concentrations of salts (Figure 13.2). Most freshwater is found as ice in the vast glaciers of Greenland and the immense ice sheets of Antarctica.
