This chart shows total surface area of earth.
Total surface area of earth: 510,072,000 sq km
- Total water surface area: 70.8% (361,132,000 sq km)
- Total land surface area: 29.2% (148,940,000 sq km)
There are a total of 5 oceans, and they are the Arctic, Pacific, Atlantic, Indian, and the Antarctic Ocean. Out of these five, there are three major oceans, the Atlantic, Pacific, and the Indian Ocean. They account for 90 percent of the area covered by oceans.
Water covers approximately 70 percent of our world's surface. Yet only 2.5 percent of the Earth's water is fresh and thus suitable for consumption. Not only that, but of that 2.5 percent, more than two-thirds is locked away in glaciers and not particularly able to help meet the growing demands of society. By far, the most abundant and available source of fresh water is underground water supplies or wellsprings known as aquifers.
The percentages of earth's land surface can be divided into different types: 20% covered by snow land, 20% mountains, 20% dry land, 30% good land that can be farmed, 10% land doesn't have topsoil.
The highest point on land is Mount Everest (8,848 metres or 29,029 ft) and the deepest known part on ocean is The Mariana Trench (11,034 metres or 36,200 ft).
