The South Pole is at an altitude of 9,200 feet (2,800 m) but feels like 11,000 feet (3,400 m). [34] Centripetal force from the spin of the planet throws the atmosphere toward the equator. The South Pole is colder than the North Pole primarily because of the elevation difference and for being in the middle of a continent. [35]
The North point will then be the point on the limb that is closest to the North celestial pole. Similarly, a line from the center to the South celestial pole will define the South point by its intersection with the limb. The points at right angles to the North and South points are the East and West points.
A top-down view of the polar latitudes of Earth's Northern Hemisphere, centered on the Geographic North Pole and showing the distinct locations of the actual Magnetic North Pole and the idealized Geomagnetic North Pole as of 2017. Only the Geographic Pole is in a stationary position; the Magnetic and Geomagnetic Poles are both gradually moving ...
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
The word north is related to the Old High German nord, [1] both descending from the Proto-Indo-European unit *ner-, meaning "left; below" as north is to left when facing the rising sun. [2] Similarly, the other cardinal directions are also related to the sun's position. [3] [4] [5]
There’s the geographic North Pole, which never changes. And there’s the magnetic North Pole, which is always on the move. And right now it’s moving faster than usual.
Direction determination refers to the ways in which a cardinal direction or compass point can be determined in navigation and wayfinding.The most direct method is using a compass (magnetic compass or gyrocompass), but indirect methods exist, based on the Sun path (unaided or by using a watch or sundial), the stars, and satellite navigation.
North and South poles are also defined for other planets or satellites in the Solar System, with a North pole being on the same side of the invariable plane as Earth's North pole. [ 2 ] Relative to Earth's surface, the geographic poles move by a few metres over periods of a few years. [ 3 ]
