The Earth's magnetic field has alternated between periods of normal polarity, in which the predominant direction of the field was ...
A geographical pole or geographic pole is either of the two points on Earth where its axis of rotation intersects its surface.

In astronomy and navigation, the celestial sphere is an abstract sphere that has an arbitrarily large radius and is concentric to Earth. All objects in the sky can be conceived as being projected upon the inner surface of the celestial sphere, which may be centered on Earth or the observer.

Prime meridian. A prime meridian is an arbitrarily -chosen meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, like Earth, into two hemispheres ...
