Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's crust.
The entire ocean, containing 97% of Earth's water, spans 70.8% of Earth's surface, [8] making it Earth's global ocean or world ocean. [ 23 ] [ 25 ] This makes Earth, along with its vibrant hydrosphere a "water world" [ 43 ] [ 44 ] or " ocean world ", [ 45 ] [ 46 ] particularly in Earth's early history when the ocean is thought to have possibly ...
Land and water hemispheres. The land hemisphere and water hemisphere are the hemispheres of Earth containing the largest possible total areas of land and ocean, respectively. By definition (assuming that the entire surface can be classified as either "land" or "ocean"), the two hemispheres do not overlap. Determinations of the hemispheres vary ...
Dymaxion world map with the 15 largest lakes roughly to scale. This is a pair of lists of terrestrial lakes with a surface area of more than approximately 3,000 square kilometres (1,200 sq mi), ranked by area, [1] [2] [3] excluding reservoirs and lagoons. The area of some lakes can vary considerably over time, either seasonally or from year to ...
Land, also known as dry land, ground, or earth, is the solid terrestrial surface of Earth not submerged by the ocean or another body of water. It makes up 29.2% of Earth's surface and includes all continents and islands. Earth's land surface is almost entirely covered by regolith, a layer of rock, soil, and minerals that forms the outer part of ...
Gulf of Guinea – 2.35 million km 2 (0.91 million sq mi) Tasman Sea – 2.3 million km 2 (0.89 million sq mi) Bay of Bengal – 2.172 million km 2 (0.839 million sq mi) Bering Sea – 2 million km 2 (0.77 million sq mi) Sea of Okhotsk – 1.583 million km 2 (0.611 million sq mi)
World map. A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
The area north of the Circle is about 20,000,000 km 2 (7,700,000 sq mi) and covers roughly 4% of Earth's surface. [ 12 ] The Arctic Circle passes through the Arctic Ocean , the Scandinavian Peninsula , North Asia , Northern America , and Greenland.
