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.

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.

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 35โฐ (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.
What Percent of Earth is Water?
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.

Water is essential for all life and is the most abundant substance on Earth.
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.
How Much Of Earthโs Surface Is Covered With Water? Watery
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.

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.

What is the percentage of earth surface which is covered by water?
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.
