Old English eorþe "ground, soil, dirt, dry land; country, district," also used (along with middangeard) for "the (material) world, the abode of man" (as opposed to the heavens or the underworld), from Proto-Germanic *ertho (cognates: Old Frisian erthe "earth," Old Saxon ertha, Old Norse jörð, Middle Dutch eerde, Dutch aarde, Old High German erda, German Erde, Gothic airþa), from extended form of PIE root *er- (2) "earth, ground" (cognates: Middle Irish -ert "earth"). The earth considered as a planet was so called from c.1400. Use in old chemistry is from 1728. Earth-mover "large digging machine" is from 1940.

Earth is one of the classical elements, in some systems numbering four along with air, fire, and water.

Earth (otherwise known as the world, in Gaia, or in Latin: Terra) is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System's four terrestrial planets, and the only astronomical object known to harbor life.

According to radiometric dating and other sources of evidence, Earth formed about 4.54 billion years ago. Earth gravitationally interacts with other objects in space, especially the Sun and the Moon. During one orbit around the Sun, Earth rotates about its own axis 366.26 times, creating 365.26 solar days or one sidereal year. Earth's axis of rotation is tilted 23.4° away from the perpendicular of its orbital plane, producing seasonal variations on the planet's surface within a period of one tropical year (365.24 solar days). The Moon, Earth's only permanent natural satellite, by its gravitational relationship with Earth, causes ocean tides, stabilizes the orientation of Earth's rotational axis, and gradually slows Earth's rotational rate.

Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. 71% of Earth's surface is covered with water. The remaining 29% is land mass—consisting of continents and islands—that together has many lakes, rivers, and other sources of water that contribute to the hydrosphere. The majority of Earth's polar regions are covered in ice, including the Antarctic ice sheet and the sea ice of the Arctic ice pack. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates the Earth's magnetic field, and a convecting mantle that drives plate tectonics.

Within its first billion years, life appeared in Earth's oceans, and began to affect the atmosphere and surface, leading to the proliferation of aerobic and anaerobic organisms. Since then, the combination of Earth's distance from the Sun, physical properties, and geological history have allowed life to evolve and today thrive. The earliest undisputed life on Earth arose at least 3.5 billion years ago. Earlier physical evidence of life includes biogenic graphite in 3.7 billion-year-old metasedimentary rocks discovered in southwestern Greenland, as well as "remains of biotic life" found in 4.1 billion-year-old rocks in Western Australia. Except when interrupted by mass extinction events, Earth's biodiversity has continually expanded. Although scholars estimate that over 99% of all species of life (over five billion) that ever lived on Earth are today extinct, there are an estimated 10–14 million species still in existence, of which about 1.2 million have been documented and over 86% have not yet been described. More recently, in May 2016, scientists reported that 1 trillion species are estimated to be on Earth currently with only one-thousandth of one percent described. In July 2016, scientists reported identifying a set of 355 genes from the Last Universal Common Ancestor (LUCA) of all organisms living on Earth. Over 7.3 billion humans live on Earth and depend on its biosphere and minerals for their survival. Earth's human population is divided among about 200 sovereign states that interact through diplomacy, conflict, travel, trade, and communication media.

Earth is the third planet from the Sun.

__NOTOC__ This article is on the history of Earth, as presented in Isaac Asimov's Foundation series, Robot series, and Empire series.

Humans from Earth colonize the Spacer and, later, Settler planets; an anti-Earth plot causes the planet's crust to become radioactive, greatly reducing its population. Many small empires rise and fall throughout the Milky Way Galaxy as various worlds trade with and fight each other. Over time one planet, Trantor, founds a true Galactic Empire. By then Earth is only one of millions of member worlds, and the radioactivity makes it a quarantined backwater; by 827 G.E. (Galactic Era, the number of years after the empire's founding), the setting of Pebble in the Sky, only 20 million people live on Earth. Most non-Earthlings are skeptical of the scholarly theory that the obscure planet is the original home of all humans, believing that humans evolved on many planets simultaneously. By 12000 G.E., the setting of the Foundation series, although many believe that humanity originated on one planet, Earth is one of several candidates.

The chemical term earths was historically applied to certain chemical substances, once thought to be elements, and this name was borrowed from one of the four classical elements of Plato. "Earths" later turned out to be chemical compounds, albeit difficult to concentrate, such as rare earths and alkaline earths.

Earths are metallic oxides, and the corresponding metals were classified into the corresponding groups: rare earth metals and alkaline earth metals.

Earth is an American musical group based in Olympia, Washington, formed in 1989 and led by the guitarist Dylan Carlson. Earth's music is nearly all instrumental, and can be divided into two distinct stages. Their early work is characterized by distortion, droning, minimalism, and lengthy, repetitive song structures. The band's later output reduces the distortion while incorporating elements of country, jazz rock, and folk. Earth is recognized as a pioneer of drone metal, with the band's Earth 2 being regarded as a milestone of the genre.

Earth is the third solo album by the Greek artist Vangelis, released in 1973. In contrast to Heaven and Hell (1975) and some soundtracks by Vangelis from this period, Earth was not released on compact disc in the 1980s — it was not until 1996 that a CD version was made available, and then only in Greece.

The album was promoted by a concert, held in Paris, at the Olympia Theatre in February 1974.

In 1974 two left-over tracks from the recording sessions for Earth were issued as a single, on the WWA label: Who, written by Fitoussi and Dassin on the A-side and featuring vocals by the former, and the instrumental Sad Face, by Vangelis himself, on the B-side.

Earth was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001. Their greatest hit, their debut single "Time After Time", peaked at #13 in the Oricon singles chart.

Earth is the second album by alternative rock musician Matthew Sweet. It was released on A&M Records in 1989.

Earth is a science fiction novel by Marie C. Farca, with an ecological theme. It published in 1972 by Doubleday in the United States.

Earth, initially credited as The Earth, was a British psychedelic music band active from 1968-1969. The band is mainly significant for having caused the band Earth formed by Ozzy Osbourne and Tony Iommi to change the name of their hard-edged blues band Earth to Black Sabbath in order to avoid confusion.

The line-up included The Misunderstood's Glenn Campbell on steel guitar and Robin Parnell on bass guitar. The band released two singles and recorded radio sessions for the BBC. After the second single Campbell disbanded Earth and formed Juicy Lucy.

Earth is a 2007 nature documentary film which depicts the diversity of wild habitats and creatures across the planet. The film begins in the Arctic in January of one year and moves southward, concluding in Antarctica in the December of the same year. Along the way, it features the journeys made by three particular species—the polar bear, African bush elephant and humpback whale—to highlight the threats to their survival in the face of rapid environmental change. A companion piece to the 2006 BBC/ Discovery television series Planet Earth, the film uses many of the same sequences, though most are edited differently, and features previously unseen footage.

Earth was co-directed by Alastair Fothergill, the executive producer of the television series, and Mark Linfield, the producer of Planet Earth's "From Pole to Pole" and "Seasonal Forests" episodes. It was co-produced by BBC Natural History Unit and Greenlight Media, with Discovery providing some of the funding. It was also the first film released under the Disneynature label. The same organisations collaborated on Fothergill's previous film, Deep Blue (2003), itself a companion to his 2001 television series on the natural history of the world's oceans, The Blue Planet. The British version of Earth was narrated by Patrick Stewart and the US version was narrated by James Earl Jones.

Earth was released in cinemas internationally during the final quarter of 2007 and throughout 2008. With total worldwide box office revenue exceeding $100 million, Earth is the second-highest grossing nature documentary of all time.

A sequel, titled Earth: One Amazing Day, is scheduled for release in 2017.

Earth is a 1978 album by Jefferson Starship. The album was recorded in 1977, with the same band lineup as the previous album, Spitfire. The band had not toured in 1977, partly due to Marty Balin's reluctance to commit fully to the band. The song "Count on Me" became a Top-10 single, peaking at #8. The album itself hit #5 on the Billboard charts. A US and European tour followed which resulted in an audience riot in Germany after the band decided not to play without Grace Slick who was ill. They lost all their guitars and equipment during the riot and played one more tense show on German TV in Hamburg after which Grace left the band for one album. Marty Balin fronted the band for one more show at a Genesis concert at the Knebworth Festival in England using rented equipment. When they returned to the USA drummer John Barbata left the band after a serious car accident. This would be the end of the 1970s line-up and several new members joined the band, as well as a new record producer. Success of this album led to Jefferson Starship being contracted to provide a song for the Star Wars Holiday Special.

In Chinese philosophy, earth , is the changing point of the matter. Earth is the third element in the Wu Xing cycle.

Earth is a balance of both yin and yang, the feminine and masculine together. Its motion is inward and centering, and its energy is stabilizing and conserving. It is associated with the color yellow and the planet Saturn, and it lies at the center of the compass in the Chinese cosmos. It is associated with the turn of each of the four seasons and with damp weather. It governs the Spleen, Stomach, mouth and muscles. Its negative emotion is anxiety and its positive emotion is empathy. Its Primal Spirit is represented by the Yellow Dragon. Colour Yellow, Golden ( Sun)
