Editing Medina (section)

===Topography===
Medina is a [[desert oasis]] surrounded by the [[Hejaz Mountains]] and volcanic hills. The soil surrounding Medina consists of mostly [[basalt]], while the hills, especially noticeable to the south of the city, are [[volcanic ash]] which dates to the first [[geological period]] of the [[Paleozoic]] Era. It is surrounded by a number of famous [[Wareqan Mountain|mountains]], most notably ''Jabal Al-Hujjaj'' (The Pilgrims' Mountain) to the west, Sal'aa Mountain to the north-west, ''Jabal al-'Ir'' or Caravan Mountain to the south and [[Mount Uhud]] to the north. The city is situated on a flat mountain plateau at the tripoint of the three valleys ([[wadi]]s) of ''Wadi al 'Aql'', ''Wadi al 'Aqiq'', and ''Wadi al Himdh'', for this reason, there are large green areas amidst a dry deserted mountainous region.<ref name=":5" />
