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.
How much of Earth's surface is covered by each country? World Economic Forum
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.
The distribution of water on, in, and above the Earth U.S. Geological Survey
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.

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

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.
