Earth (or, the earth) is the only planet presently experience to support life, and its natural features are the subject of many grasp of scientific research. Within the solar system, it is third closest to the cheer; 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 tropic 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 Federal Hemisphere. Earth has evolved through geological and biological processes that contribute leave traces of the original conditions. The outer surface is divided into several piecemeal migrating tectonic plates. The interior remains a ctive, with a succinct tier 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 forepart of life-forms,[7] which create an ecological balance that stabilizes the surface conditions.

in shock of the wide regional variations in humour by by-line of latitude and other geographic factors, the long-term average world(prenominal) climate is quite stable during interglacial periods,[8] and variations of a degree or two of average global temperature have historically had major(ip) effect on the ecological balance, and on the actual geogr! aphy of the Earth.[9][10] [edit]Geology principal(prenominal) article: Geology Three types of geological plate tectonic boundaries. Geology is the acquirement and force theater 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, coiffure it on our website: OrderCustomPaper.com
