Earth is the 3rd planet from the Sun and the only astronomical thing known to harbor life. Based on radiometric dating and some other sources of evidence, Planet formed over 4. 5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Celestial body overhead, Earth's only natural satellite television. Earth revolves around sunlight in 365. 26 days and nights, a period known as an Earth year. Throughout this time, Earth rotates about its axis about 366. 26 times.
Globe's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes sea tides, stabilizes Earth's alignment on its axis, and progressively slows its rotation. Earth is the densest planet in the Sun System and the largest of the four terrestrial planets.
Earth's lithosphere is divided into several firm tectonic plates that move across the surface over periods of many hundreds of thousands of years. About 71% of Earth's surface is covered with water, mainly by oceans. The 29% is land comprising continents and islands that with each other have many lakes, rivers and other sources of water that contribute to the hydrosphere. Nearly all 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 just the first billion years of Earth's history, life appeared in the seas and began to affect the Earth's atmosphere and surface, leading to the proliferation of aerobic and anaerobic organisms. Some geological evidence indicates that life could have arisen as much as 4. 1 billion years ago. Since then, the mixture of Globe's distance from the Sunshine, physical properties, and geological history have allowed life to evolve and prosper. In the good the Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinction events. Over 99% of species that ever lived on Planet are extinct. Estimates of the number of varieties on the planet today vary broadly; most species have not been described. Over 7. 6 billion humans live on Earth and count on its biosphere and natural resources for their survival.[40] Humans are suffering from diverse societies and ethnicities; politically, the world has about 200 sovereign says.
The modern English word World developed from a large variety of Middle British forms, which derived from a vintage English noun most often spelled eorðe. That has cognates in every Germanic language, and their proto-Germanic root has been reconstructed as *erþō. In its earliest appearances, eorðe was already being utilized to convert the many senses of Latin terra and Greek γῆ (gē): the floor, the soil, dry land, a persons world, the surface of the world (including the sea), and the globe itself. As with Terra and Gaia, Earth was a personified goddess in Germanic paganism: the Angles were posted by Tacitus as among the devotees of Nerthus, and later Norse mythology included Jörð, a giantess often given as the mother of Thor.
Originally, earth was written in lowercase, and from early Center English, its definite sense as "the globe" was expressed as the planet. By Early Modern The english language, many nouns were capitalized, and the earth became (and often remained) the Earth, particularly when referenced alongside with other heavenly body. More recently, the name is sometimes simply given as Earth, by analogy with the names of some other planets. House styles now vary: Oxford spelling acknowledges the lowercase form as the utmost common, with the capitalized form an acceptable version. Another convention capitalizes "Earth" when appearing as a name (e. g. "Earth's atmosphere") but writes it in lowercase when forwent by the (e. gary the gadget guy. "the atmosphere of the earth"). It almost always appears in lowercase in colloquial expressions such as "what on earth are you doing? ".
