Either extremity of an axis of a sphere; especially, one of the extremities of the earth's axis; as, the north pole.
A point upon the surface of a sphere equally distant from every part of the circumference of a great circle; or the point in which a diameter of the sphere perpendicular to the plane of such circle meets the surface. Such a point is called the pole of that circle; as, the pole of the horizon; the pole of the ecliptic; the pole of a given meridian.
One of the opposite or contrasted parts or directions in which a polar force is manifested; a point of maximum intensity of a force which has two such points, or which has polarity; as, the poles of a magnet; the north pole of a needle.
See Polarity, and Polar, n.
The point at either end of the invisible line known as the axis. Planets have a south pole and a north pole. RADIO WAVE A type of energy that is made by charged particles such as electrons moving back and forth.
(1) One of two points on the Earth's surface where the Earth's rotational axis intersects the Earth's surface. (2) One of two points on the surface of the Earth equidistant from the equator. (3) The origin of a polar coordinate system.
Usually the coldest regions on a planet, being the areas around an axis through the planet perpendicular to the plane of rotation about the Sun.
end of an axis, or the point where an axis meets the surface of a planet (geographic); either end of a magnet and points where the magnetic forces originate (magnetic).
noun - A point on a planet where the axis of rotation and the surface of the planet intersect. A planet in realmspace has two poles, but a planet in tetraspace has two equators instead - each equator functions as the other equator's pole.
( Wodehouse, 1935) Either of the two extremities of the polar axis. See also: polar axis.
See polar origin.
The imaginary points on the globe through which the axis of rotation runs.
The geographic poles are the two extremes of the axis around which the Earth spins. The North Pole is 90° north of the Equator and the South Pole is 90° south of the Equator, so both poles are equidistant from the Equator.
Point at which Axis of Rotation of a Sphere Meets its Surface
one of two points of intersection of the Earth's axis and the celestial sphere
one of two antipodal points where the Earth's axis of rotation intersects the Earth's surface
a point that, in the presence of a circle, is paired with a straight line - its polar with respect to the circle
a point that, in the presence of an angle, is paired with a straight line - its polar with respect to the angle
the point at which a planets axis of rotation crosses the planet
The topmost (northern) or bottomost (southern) points of a sphere . (See Modeling the Earth-Sun System )
The intersections of the surface of a body and its axis of rotation.
Either end of the axis of any sphere such as the Earth, the celestial sphere, etc.
The term pole refers to either end of the axis of rotation of the earth, that is the North Pole and the South Pole.
1. A point in an electromagnetic field at which electric or magnetic field lines converge. See also dipole, magnetic dipole. 2. For any circle on the surface of a sphere, the point of intersection of the surface of the sphere and the normal line through the center of the circle. The North and South geographic poles are the poles of the equator or of any other latitude circle. 3. The origin of a system of polar coordinates.
