Home > Polar region
Earth's polar regions are the areas of the globe surrounding the poles, within the Arctic and Antarctic Circles. They are characterised by extremely cold temperatures, heavy glaciation, and extreme variations in daylight hours, with 24 hour daylight in Summer (the Midnight sun), and permanent darkness at mid- Winter.There are many settlements in Earth's north polar regions, but none except for scientific bases in the south polar regions, which are colder than the northern polar regions.
Other planets and natural satellites in the Solar system have interesting quirks about their polar regions. Earth's Moon is thought to contain substantial deposits of ice in deep craters in its polar regions, which never see direct sunlight. Mars, like Earth, has polar cap s, but unlike Earth's icy caps they consist mostly of carbon dioxideCarbon dioxide is an atmospheric gas composed of one carbon and two oxygen atoms. One of the best known of chemical compounds, it is frequently called by its formula: :CO (pronunciation: "see oh two") Carbon dioxide results from the combustion of organic. On UranusUranus (pronounced "YOOR--nus", or "yr-AYN-us") is the seventh planet from the Sun. It is a gas giant and the third largest by diameter. It was named after the Greek god Ouranos. Its symbol is either Unicode ♅ (mostly astrological) or (mostly astro, meanwhile, the extreme tilt of the planet's axis leads to the unique situation during the Uranian year of first one pole and then the other pointing almost directly at the SunThe Sun (also called Sol is the star in our solar system. Planet Earth orbits the Sun. Other bodies that orbit the Sun include other planets, asteroids, meteoroids, comets and dust. Not all objects passing through the solar system have been orbitally capt.

There are various ways of defining a planet's North Pole. Earth's Pole, however it is defined, lies in the Arctic Ocean. Defini, South PoleAntarctic Treaty signatories are arrayed around it, and the Pole Station's old dome is in the background. The polar ice cap and the South Pole station on it are constantly moving relative to the actual, Geographic South Pole. The South Pole is the souther.
GeographyGeography is the scientific study of the locational and spatial variation in both physical and human phenomena on Earth. The word derives from the Greek words g ("the Earth") and graphein ("to write," as in "to describe"). Geography is also the title of v
