How much water is in the ocean? About 97 percent of Earth's water is in the ocean. The ocean covers more than 70 percent of the surface of our planet. It's hard to imagine, but about 97 percent of the Earth's water can be found in our oceans. Of the tiny percentage that's not in the ocean, about two percent is frozen up in glaciers and ice caps. Less than one percent of all the water on Earth is fresh. A tiny fraction of water exists as water vapor in our atmosphere.

What percent of Earth is water? In simplest terms, water makes up about 71% of the Earth’s surface, while the other 29% consists of continents and islands. To break the numbers down, 96.5% of all the Earth’s water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact. If you could melt all that ice, and the Earth’s surface was perfectly smooth, the sea levels would rise to an altitude of 2.7 km.

The Earth has lost a quarter of its water This finding can be used to show that back in time there was more water on Earth than today. (Photo:Colourbox) Although water covers 70 percent of the Earth's surface, water is actually a rare substance that represents just 0.05 percent of the Earth's total mass. Water has nevertheless played a crucial role in the emergence of life on Earth.

What percent of Earth is water? But how much of Earth is water — how much water contributes to the actual mass of the planet? This includes not just the surface of the Earth, but inside as well. Scientists calculate that the total mass of the oceans on Earth is 1.35 x 10 18 metric tonnes, which is 1/4400 the total mass of the Earth. In other words, while the oceans cover 71% of the Earth’s surface, they only account for 0.02% of our planet’s total mass.

How much water is there on Earth? ­The oceans are huge. About 70 percent of the planet is covered in ocean, and the average depth of the ocean is several thousand feet (about 1,000 meters). Ninety-eight percent of the water on the planet is in the oceans, and therefore is unusable for drinking because of the salt. About 2 percent of the planet's water is fresh, but 1.6 percent of the planet's water is locked up in the polar ice caps and glaciers. Another 0.36 percent is found underground in aquifers and wells. Only about 0.036 percent of the planet's total water supply is found in lakes and rivers.

What Is the Land to Water Ratio on Earth? More than 68 percent of the planet's fresh water is largely inaccessible, located in glaciers, ice caps and permanent snow. Another 30 percent of the planet's fresh water is located in the ground, within a half-mile of the Earth's surface. The amount of water located on Earth is enough to cover the entire land mass of the contiguous United States to a depth of 107 miles.

- People tend to think that the amount of water on the planet is unlimited, yet the amount of water on the Earth will actually stay the same. Of the water on Earth, 97.3% is oceans, inland seas, and salt lakes; the rest is fresh water (icecaps/glaciers, groundwater, freshwater lakes, atmosphere, rivers). The amount of available fresh water to humans and wildlife depends largely on how water quality is maintained.

Where is all of the Earth's water? Where is all of the Earth's water? 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. The ocean holds about 97 percent of the Earth's water; the remaining three percent is distributed in many different places, including glaciers and ice, below the ground, in rivers and lakes, and in the atmosphere. According to the U.S. Geological Survey, there are over 332,519,000 cubic miles of water on the planet. A cubic mile is the volume of a cube measuring one mile on each side. Of this vast volume of water, NOAA's National Geophysical Data Center estimates that 321,003,271 cubic miles is in the ocean.

How much water is there on, in, and above the Earth? That one represents fresh water in all the lakes and rivers on the planet. Most of the water people and life on earth need every day comes from these surface-water sources. The volume of this sphere is about 22,339 mi 3 (93,113 km 3). The diameter of this sphere is about 34.9 miles (56.2 kilometers).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.
