Full Answer
There are over 510 million square kilometers of area on the surface of Earth, but less than 30% of this is covered by land. The rest is water, in the form of vast oceans. Today’s visualization uses data primarily from the United Nations Statistics Division (UNSD) to rank the world’s countries by their share of Earth’s surface.
The largest countries by surface area are Russia (3.35%), Canada (1.96%), and China (1.88%). Together they occupy roughly 7.2% of Earth’s surface. Russia is so big that even if we divided the country between its Asian and European sections, those new regions would still be the largest in their respective continents.

The Earth is a watery place. But just how much water exists on, in, and above our planet? About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water.
70 percentThe 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 ocean. Of the tiny percentage that's not in the ocean, about two percent is frozen up in glaciers and ice caps.
"The world ocean covers 71 percent of the earth's surface, or about 361 million sq km (140 million sq mi). Its average depth is 5,000 m (16,000 ft), and its total volume is about 1,347,000,000 cu km (322,300,000 cu mi)."...Volume of Earth's Oceans.NamePacific OceanAreasq. mi.64,000,000sq. km165,760,000Average Depthft.13,215m4,0283 more columns
Over 97 percent of the earth's water is found in the oceans as salt water. Two percent of the earth's water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth's water available to us for our daily water supply needs.
Less than 30% of the 510 million square kilometers of area on the Earth's surface is covered by land. There are over 510 million square kilometers of area on the surface of Earth, but less than 30% of this is covered by land. The rest is water, in the form of vast oceans.
71% of the earth's surface is water-covered, and the ocean holds about 96.5 per cent of all Earth's water. Water also exists in the form of water vapour, rivers and lakes.
In simplest terms, water makes up about 71% of the Earth's surface, while the other 29% consists of continents and islands.
The Earth is a watery planet, the only one of its kind in the solar system. A full 71% of the Earth's surface is covered with water, with land comprising the remaining 29%.
waterNearly three-fourths of the earth's surface is covered with water. 97% of the water on the Earth is salt water and only three percent is fresh water.
Only about three percent of Earth's water is freshwater. Of that, only about 1.2 percent can be used as drinking water; the rest is locked up in glaciers, ice caps, and permafrost, or buried deep in the ground. Most of our drinking water comes from rivers and streams.
About 2.1% of all of Earth's water is frozen in glaciers.
Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries - including the United States - now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are the most commonly known.
