Natural Earth is a public domain map dataset available at 1:10 million (1 cm = 100 km), 1:50 million, and 1:110 million map scales. [ clarification needed ] Natural Earth's data set contains integrated vector and raster mapping data.
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 natural history of Earth concerns the development of planet Earth from its formation to the present day. [ 1 ] [ 2 ] Nearly all branches of natural science have contributed to understanding of the main events of Earth's past, characterized by constant geological change and biological evolution .
Of the Solar System's eight planets and its nine most likely dwarf planets, six planets and seven dwarf planets are known to be orbited by at least 300 natural satellites, or moons. At least 19 of them are large enough to be gravitationally rounded; of these, all are covered by a crust of ice except for Earth's Moon and Jupiter's Io. [1]

The Natural Earth projection is a pseudocylindrical map projection designed by Tom Patterson and introduced in 2008. [1] It is neither conformal nor equal-area, but a compromise between the two. In its original presentation, the projection's origin is described as "The impetus for creating the Natural Earth projection was dissatisfaction with ...
Earth science or geoscience includes all fields of natural science related to the planet Earth. [1] This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere , hydrosphere / cryosphere , atmosphere , and geosphere (or lithosphere ).
