GEOLOGY

Detailed explanation-1: -Surface water is a key component to the hydrologic cycle. Surface water is any body of water above ground, including streams, rivers, lakes, wetlands, reservoirs, and creeks. The ocean, despite being saltwater, is also considered surface water.

Detailed explanation-2: -Fresh water is found in glaciers, lakes, reservoirs, ponds, rivers, streams, wetlands and even groundwater. These freshwater habitats are less than 1% of the world’s total surface area yet house 10% of all known animals and up to 40% of all known fish species.

Detailed explanation-3: -Fresh surface-water sources, such as rivers and lakes, only constitute about 22, 300 cubic miles (93, 100 cubic kilometers), which is about 1/150th of one percent of total water.

Detailed explanation-4: -Surface water collects on the ground or in a stream, river, lake, reservoir, or ocean. Surface water is constantly evaporating out of water bodies, seeping into ground water supplies, and being replenished by rain and snow.
