In geography, the antipodes (; from Greek: ἀντίποδες,〔(Antipodes ), Liddell and Scott, "A Greek-English Lexicon", at Perseus.〕 from ''anti-'' "opposed" and ''pous'' "foot") of any place on Earth is the point on the Earth's surface which is diametrically opposite to it. Two points that are ''antipodal'' to each other are connected by a straight line running through the centre of the Earth. In the Northern Hemisphere, "the Antipodes" may be used to refer to Australia and New Zealand, and "Antipodeans" to their inhabitants.〔(Compact Oxford English Dictionary, 2008, "Antipodes" ) Access date: 2010-02-21.〕 Geographically the antipodes of Britain and Ireland are in the Pacific Ocean, south of New Zealand. This gave rise to the name of the Antipodes Islands of New Zealand, which are close to the antipodes of London at about 50° S 179° E. The antipodes of Australia are in the North Atlantic Ocean, while parts of Spain, Portugal, and Morocco are antipodal to New Zealand. Approximately 15% of land territory is antipodal to other land, representing approximately 4.4% of the Earth's surface. The largest antipodal land masses are the Malay Archipelago, antipodal to the Amazon Basin and adjoining Andean ranges; east China and Mongolia, antipodal to Chile and Argentina; and Greenland and the Canadian Arctic Archipelago, antipodal to East Antarctica. == Geography == The antipodes of any place on the Earth is the place that is diametrically opposite it, so a line drawn from the one to the other passes through the centre of the Earth and forms a true diameter. For example, the antipodes of New Zealand's lower North Island lies in Spain. Most of the Earth's land surfaces have ocean at their antipodes, this being a consequence of most land being in the land hemisphere. An antipodal point is sometimes called an ''antipode'', a back-formation from the plural ''antipodes'', which in Greek is the plural of the singular ''antipous''. The antipodes of any place on Earth are distant from it by 180° of longitude and as many degrees to the north of the equator as the original is to the south (or vice versa); in other words, the latitudes are numerically equal, but one is north and the other south. The maps shown here are based on this relationship; they show a Lambert azimuthal equal-area projection of the Earth, in yellow, overlaid on which is another map, in blue, shifted horizontally by 180° of longitude and inverted about the equator with respect to latitude. Noon at one place is midnight at the other (ignoring daylight saving time and irregularly shaped time zones) and, with the exception of the tropics, the longest day at one point corresponds to the shortest day at the other, and midwinter at one point coincides with midsummer at the other. Sunrise and sunset do not quite oppose each other at antipodes due to refraction of sunlight. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「antipodes」の詳細全文を読む スポンサード リンク
