Earth's polar regions come a areas of a earth surrounding the poles, north of the Arctic circle, or south of the Antarctic Circle. It is characterized per polar climate, extremely cold temperatures, heavily glaciation, and extreme variations around daylight hours, by owning Two dozen hour daylight around summer (the midnight sun), and lasting darkness at mid-winter. A North Pole and South Pole being the centres, these regions come dominated per polar ice caps, resting respectively in ocean and the continent of Antarctica. There are numbers of settlements within Globe's northwards polar zone, however none except for scientific bases south frigid zone, which are then colder than a northern frigid zone. More planets and natural satellites in the solar system have interesting quirks about their frigid zone. Globe's Moon is thought to contain substantial deposits of ice in deep craters in its frigid zone, which never understand directly sunlight. Mars, like Globe, has polar caps, but unlike Globe's icy caps it consist mostly of carbon dioxide. In Uranus, meanwhile, the extreme tilt of the planet's axis leads to a unique situation when you took a Uranian season of number a single one pole so a more pointing nigh directly at the Sun.
