The pedosphere is the outermost layer of Earth's land surface and is composed of soil and subject to soil formation processes. Soil is crucial for land to be arable. Earth's total arable land is 10.7% of the land surface, with 1.3% being permanent cropland.
Dymaxion map of the world with the 30 largest countries and territories by area. This is a list of the world's countries and their dependencies, ranked by total area, including land and water. This list includes entries that are not limited to those in the ISO 3166-1 standard, which covers sovereign states and dependent territories.
Land is often defined as the solid, dry surface of Earth. [1] The word land may also collectively refer the collective natural resources of Earth, [2] including its land cover, rivers, shallow lakes, its biosphere, the lowest layer of the atmosphere (troposphere), groundwater reserves, and the physical results of human activity on land, such as architecture and agriculture.

Asia is the largest continent on Earth. It covers 9% of the Earth's total surface area (or 30% of its land area), and has the longest coastline, at 62,800 kilometres (39,022 mi). Asia is generally defined as comprising the eastern four-fifths of Eurasia.
Myers's original circle covers only about 10% of the Earth's total surface area, with a radius of around 4,000 kilometers (2,500 miles), centered in the South China Sea. [1] The map became a popular meme , and was featured in numerous internet media outlets.
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 slightly. One determination places the centre of the land hemisphere at 47°13′N 1°32′W / 47.217°N 1.533°W / 47.217; -1.533 (in the city of Nantes , France
