How is water found? The ocean holds about 97 percent of the Earth’s water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world’s total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.
Where is fresh water found? 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.
In what forms is fresh water found on the earth? Although in warm periods such as the Mesozoic and Paleogene when there were no glaciers anywhere on the planet all fresh water was found in rivers and streams, today most fresh water exists in the form of ice, snow, groundwater and soil moisture, with only 0.3% in liquid form on the surface.

Why is water so special?
Water’s importance to life functions all attribute to its polarity, hydrogen bonding and density. Water is a polar molecule: constructed of one oxygen atom and two hydrogen atoms, the oxygen is considerably more electronegative than the hydrogen.

What percent of salt water is on Earth?
97 percent
Over 97 percent of the earth’s water is found in the oceans as salt water. Two percent of the earth’s water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth’s water available to us for our daily water supply needs.
