About Earth in brief

Summary Earth Earth is the third planet from the Sun and the only astronomical object known to harbor life. About 29% of Earth’s surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water. Over 99% of all species that ever lived on Earth are extinct. Almost 8 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Earth is the densest planet in the Solar System and the largest and most massive of the four rocky planets. The modern English word Earth developed, via Middle English, from an Old English noun most often spelled eorðe. It has cognates in every Germanic language, and their ancestral root has been reconstructed as *erþō. As with Roman TerraTellūs and Greek Gaia, Earth may have been a personified goddess in Germanic paganism: late Norse mythology included Jörð, a giantess often given as the mother of Thor. There are a number of adjectives for the planet Earth, including Earth, Terra, Terra, Terri, Terr, Ter, Ter and Terr. The name Terra is used in scientific writing and science fiction to distinguish humanity’s planet from others, while in poetry Tellus has been used to denote the Earth. From the Latin terra comes Terra ˈtɛl’s, which comes from the Latin Terr terra, which means Earth in more than one language. It is also known as Terra Terra or Terra Terra in Latin, which is more than the more common Terra terra in which its pronunciation is in which case it is spelled in lowercase.

Tropical regions receive more energy from the sun than polar regions. Greenhouse gases also play an important role in regulating the surface temperature. Extreme weather, such as tropical cyclones and heat waves, occurs in most areas and has a large impact on life. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth’s orientation on its axis, and gradually slows its rotation. Earth orbits around the Sun in about 365. 25 days.
