In geography, the antipode (/ ˈ æ n t ɪ ˌ p oʊ d, æ n ˈ t ɪ p ə d i /) of any spot on Earth is the point on Earth's surface diametrically opposite to it. A pair of points antipodal (/ æ n ˈ t ɪ p ə d əl /) to each other are situated such that a straight line connecting the two would pass through Earth's center. Antipodal points ...
Each 45×90 point is the antipode – the point on the opposite side of Earth – of another 45×90 point. The southern Indian Ocean location and the point in Wisconsin are antipodes of each other. The southern Pacific Ocean location and the point in China are antipodes of each other.
The case = can be illustrated by saying that there always exist a pair of opposite points on the Earth's equator with the same temperature. The same is true for any circle. This assumes the temperature varies continuously in space, which is, however, not always the case. [1]
The point antipodal to a given point is called its antipodes, from the Greek ἀντίποδες (antípodes) meaning "opposite feet"; see Antipodes § Etymology. Sometimes the s is dropped, and this is rendered antipode , a back-formation .
The antipode of Point Nemo – the point on the surface of the Earth that is diametrically opposite of it – is located at roughly , in the Aktobe region of western Kazakhstan, roughly 50 km (30 miles) SSE of the town of Shubarkuduk
The geomagnetic poles are antipodal points where the axis of a best-fitting dipole intersects the surface of Earth. This theoretical dipole is equivalent to a powerful bar magnet at the center of Earth , and comes closer than any other point dipole model to describing the magnetic field observed at Earth's surface.
On Earth, the prime and 180th meridians form a great ellipse that divides the planet into the Western and Eastern Hemispheres. The antimeridian passes mostly through the open waters of the Pacific Ocean but also runs across land in Russia , Fiji , and Antarctica .
A diagram illustrating great-circle distance (drawn in red) between two points on a sphere, P and Q. Two antipodal points, u and v are also shown.. The great-circle distance, orthodromic distance, or spherical distance is the distance between two points on a sphere, measured along the great-circle arc between them.
