Earth (or, the earth) is the only planet presently fuck to support life, and its natural features atomic number 18 the subject of many insure of scientific research. Within the solar system, it is third closest to the sunniness; it is the largest terrestrial planet and the fifth largest overall. Its most prominent climatical features are its devil large polar regions, two comparatively narrow temperate zones, and a wide equatorial equatorial to subtropical region.[6] Precipitation varies widely with location, from several(prenominal) metres of water per class to less(prenominal) than a millimetre. 71 percent of the Earths surface is cover by salt-water oceans. The remainder consists of continents and islands, with most of the inhabited land in the northern Hemisphere. Earth has evolved through geological and biological processes that contribute go forth traces of the original conditions. The outer surface is divided into several piecemeal migrating tectonic plates. Th e interior remains active, with a succinct mold of plastic mantle and an iron-filled core that generates a magnetised battleground. The atmospherical conditions have been significantly altered from the original conditions by the heraldic bearing of life-forms,[7] which create an ecological balance that stabilizes the surface conditions.

in venom of the wide regional variations in humour by fund of latitude and other geographic factors, the long-term average planetary climate is quite stable during interglacial periods,[8] and variations of a degree or two of average global temperature have historically ha d study effect on the ecological balance, ! and on the actual geography of the Earth.[9][10] [edit]Geology principal(prenominal) article: Geology Three types of geological plate tectonic boundaries. Geology is the action and force cranial orbit of the solid and liquid matter that constitutes the Earth. The field of geology encompasses the study of the composition, structure, physical properties, dynamics, and history of Earth materials, and the processes by which they are formed, moved, and changed. The field is...If you want to get a full essay, nightspot it on our website: OrderCustomPaper.com
