North Pole

Northern end of the Earth's geographic axis, located at latitude 90° N. It is the northern point from which all meridians of longitude start. Lying in the Arctic Ocean and covered with drifting pack ice, it has six months of constant sunlight and six months of total darkness each year. Robert E. Peary claimed to have reached the pole by dogsled in 1909, but that is now in dispute; Roald Amundsen and Richard E. Byrd claimed to have reached it by air in 1926. The geographic pole does not coincide with the magnetic North Pole, which in the early 21st century lay at about 82°45′ N, 114°25′ W, or with the geomagnetic North Pole, which is at about 79°45′ N, 71°45′ W.

North Pole

1. the northernmost point on the earth's axis, at a latitude of 90?N

2. Astronomy the point of intersection of the earth's extended axis and the northern half of the celestial sphere, lying about 1? from Polaris

3. the pole of a freely suspended magnet, which is attracted to the earth's magnetic North Pole

north pole [′nȯrth ′pōl]

(astronomy)

The north celestial pole that indicates the zenith of the heavens when viewed from the north geographic pole.

(electromagnetism)

The pole of a magnet at which magnetic lines of force are considered as leaving the magnet; the lines enter the south pole; if the magnet is freely suspended, its north pole points toward the north geomagnetic pole. Also known as positive pole.

(geophysics)

The geomagnetic pole in the Northern Hemisphere, at approximately latitude 78.5°N, longitude 69°W. Also known as north magnetic pole; north geomagnetic pole.

North Pole [′nȯrth ′pōl]

(geography)

The geographic pole located at latitude 90°N in the Northern Hemisphere of the earth; it is the northernmost point of the earth, and the northern extremity of the earth's axis of rotation. Also known as north geographic pole.

North Pole

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.)
