 | | Earth's polar regions are the areas of the globe surrounding the poles, north of the Arctic circle, or south of the Antarctic Circle. |
 | | They are characterised by the polar climate, 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. |
 | | The North Pole and South Pole being the centres, these regions are dominated by the polar ice caps, resting respectively on ocean and the continent of Antartica. |
