Oman (/oʊˈmɑːn/ (About this soundlisten) oh-MAHN; Arabic: عمان ʻumān [ʕʊˈmaːn]), officially the Sultanate of Oman (Arabic: سلطنة عُمان Salṭanat ʻUmān), is an Arab country on the southeastern coast of the Arabian Peninsula in Western Asia. Its official religion is Islam.
Holding a strategically important position at the mouth of the Persian Gulf, the country shares land borders with the United Arab Emirates to the northwest, Saudi Arabia to the west, and Yemen to the southwest, and shares marine borders with Iran and Pakistan. The coast is formed by the Arabian Sea on the southeast and the Gulf of Oman on the northeast. The Madha and Musandam exclaves are surrounded by the UAE on their land borders, with the Strait of Hormuz (which it shares with Iran) and Gulf of Oman forming Musandam's coastal boundaries
Oman lies between latitudes 16° and 28° N, and longitudes 52° and 60° E. A vast gravel desert plain covers most of central Oman, with mountain ranges along the north (Al Hajar Mountains) and southeast coast (Qara or Dhofar Mountains),[41][42] where the country's main cities are also located: the capital city Muscat, Sohar and Sur in the north, and Salalah in the south. Oman's climate is hot and dry in the interior and humid along the coast. During past epochs, Oman was covered by ocean, witnessed by the large numbers of fossilized shells existing in areas of the desert away from the modern coastline.
