How Much of the Earth is Water? 97% of the earth's water is in the oceans. Approximately 71% of the earth's surface is covered by water. The oceans and the seas account for 97%. The rest exists as water vapor, in lakes and rivers, glaciers and ice caps, in the soil and underground, aquifers, and even in living organisms.

The results, shown in the map above, revealed that between 1985 and 2015 around 173,000 square kilometers (67,000 square miles) of water were transformed into land and 115,000 square kilometers.

But in terms of mas, scientists calculate that the oceans on Earth weight about 1.35 x 10 18 metric tonnes (1.488 x 10 18 US tons), which is the equivalent of 1.35 billion trillion kg, or 2976.

Only 1% of the world's water is easily available for human consumption and use. In total, approximately 70% of the earth consists of water, but only about 2.5% of this water is freshwater. The term freshwater, also known as sweet water, describes water that occurs naturally apart from brackish water and seawater.
Water is essential for all life and is the most abundant substance on Earth.
0.5% of the earth's water is available fresh water. If the world's water supply were only 100 liters (26 gallons), our usable water supply of fresh water would be only about 0.003 liter (one-half teaspoon). In actuality, that amounts to an average of 8.4 million liters (2.2 million gallons) for each person on earth.

Most water in Earth's atmosphere and crust comes from saline seawater, while freshwater accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.

It's roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey. Some 72 percent of Earth is covered in water, but 97.

Just 3.5 percent of the water on Earth is fresh water we can drink. And most of that fresh water, 68 percent, is trapped in ice and glaciers. A third of the fresh water is in the ground. We call it groundwater. The last two percent of fresh water is in the rivers, lakes, and streams.

70% of Earth's surface is water, more specifically 27% territorial waters and 43% international waters or areas beyond national jurisdiction. The size of a country can be affected by many factors and borders can change over time. Less than 30% of the 510 million square kilometers of area on the Earth's surface is covered by land.

It suggests that most of Earth's water was on the surface at that time, during the Archean Eon between 2.5 and 4 billion years ago, with much less in the mantle. The planet's surface may have.

What is the percentage of earth surface which is covered by water?
While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.

Earth's water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground. For an estimated explanation of where Earth's water exists, look at this bar chart.

According to scientists, the total mass of the Earth's seas is 1.35 x 1018 metric tonnes, or 1/4400 the overall mass. In other words, although covering 71% of the Earth's surface, the waters constitute only 0.02% of our planet's overall mass.
