Freshwater is located in, on and above the Earth. It is found in freshwater lakes, rivers, swamps, creeks, estuaries, icebergs, glaciers and manmade reservoirs. Minute amounts of water are present in the atmosphere, in the soil and in biological organisms. Freshwater can also be found a few miles off the ground.Continue Reading
Nearly 97 percent of the world's water is saline or sea water, while freshwater or surface water makes up roughly 3 percent of the total water supply. Roughly 30 percent of this surface water is groundwater, while glaciers and ice caps make up the remaining 70 percent. Permanent ice located in the polar regions and mountain glaciers are the largest surface water storage in the world. Icebergs, glaciers and lake ice form from freshwater sources. Most icebergs and glaciers have been consistently solid for up to 15,000 years.
Billions of people around the world depend on groundwater as their main freshwater supply. The supply of groundwater is replenished by rain, snow, hail and other water sources that seep through the ground and move down into the water table. In the United States, freshwater sources are surface water or water from dams and manmade lakes. The water is generally treated and distributed as drinking water for public use, irrigation purposes and for use in the thermoelectric power supply to cool electricity-generating equipment.Learn more about Bodies of Water
Plate tectonics and reversals of the Earth's magnetic field are responsible for the magnetic stripes found on the ocean floor. When magma flows out of a mid-ocean ridge, small, magnetic minerals in the magma align themselves to point in the direction of the Earth's current magnetic North. Over time, the Earth's magnetic field reverses its north-to-south polarity, and the magnetic minerals point in the opposite direction, creating a striped pattern.Full Answer >
The Earth's five oceans are: the Pacific, the Atlantic, the Indian, the Southern and the Arctic. Whereas the Pacific Ocean is the largest, spanning 60,060,700 square miles, the Arctic is the smallest, extending only 5,427,000 square miles.Full Answer >
Large bodies of water will impact the temperature by releasing energy slowly and absorbing heat from the Sun, which cools areas that are near large bodies of water and moderates the Earth's temperature. The process begins with with the Sun's energy and the radiation that comes off of the Earth's surface.Full Answer >
The saltiest water on Earth is Don Juan Pond in Antarctica. It has a salt content of 44 percent. By contrast, the world's oceans average about 3.5 percent salt content.Full Answer >
