:''This article is about the geological rift valley, see Jordan Valley (Middle East) for cultural/geographical content.'' The Jordan Rift Valley ((アラビア語:الغور) ''Al-Ghor'' or ''Al-Ghawr''; ''Bik'at HaYarden'') is an elongated depression located in modern-day Israel, Jordan, and Palestine. This geographic region includes the entire length of the Jordan River – from its sources, through the Hula Valley, the Korazim block, the Sea of Galilee, the (Lower) Jordan Valley, all the way to the Dead Sea, the lowest land elevation on Earth – and then continues through the Arabah depression, the Gulf of Aqaba whose shorelines it incorporates, until finally reaching the Red Sea. ==History and physical features== The Jordan Rift Valley was formed many millions of years ago in the Miocene epoch (23.8 - 5.3 Myr ago) when the Arabian Plate moved northward and then eastward away from Africa. One million years later, the land between the Mediterranean and the Jordan Rift Valley rose so that the sea water stopped flooding the area. The geological and environmental evolution of the valley since its inception in the Oligocene can be seen in a variety of sedimentary and magmatic rock units, preserved as continuous sequences in the deeper basins. The outcropping formations around the basins represent alternating deposition and erosion phases.〔(The Jordan Rift Valley ), Tel Aviv University〕 The lowest point in the Jordan Rift Valley is in the Dead Sea, the lowest spot of which is 790 metres below sea level. The shore of the Dead Sea is the lowest land on earth, at 400 meters (about 1300 feet) below sea level. Rising sharply to almost 1,000 meters (almost 3,300 feet) in the west, and similarly in the east, the rift is a significant topographic feature over which a few narrow paved roads and difficult mountain tracks lead. The valley north of the Dead Sea has long been a site of agriculture because of water available from the Jordan River and numerous springs located on the valley's flanks. 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「Jordan Rift Valley」の詳細全文を読む スポンサード リンク
