the point at which the earth’s imaginary axis of rotation intersects the earth’s surface in the northern hemisphere. All other points on the surface of the earth are south of the north pole.
The north pole is located in the central part of the Arctic Ocean, where depths exceed 4,000 m. At all times the region is covered by thick multi-year pack ice. The average temperature is about -40°C in winter and about 0°C in summer; on a few summer days it rises to 1 °-2°C. The sun does not drop below the horizon for a period of 186 days and 10 hours. Because of the refraction of light, however, the polar day is actually longer than this period and lasts about 193 days. The polar night accordingly lasts 172 days, although the sun does not rise above the horizon for a period of 178 days and 14 hours. (See alsoGEOGRAPHIC POLES.)
