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.

About 70% of the surface of our planet Earth is covered in water. We are nestled in our solar system at just the right distance from the Sun for this liquid water to exist.

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.

Earth’s water distribution Earth, Groundwater, Surface water
More than 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps. Of all the water on Earth, more than 99 percent of Earth's water is unusable by humans and many other living.

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.

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.

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.
What is the percentage of earth surface which is covered by water?
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.
Water is essential for all life and is the most abundant substance on Earth.
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.
