Arabian Peninsula

Pen/cape · 297,867 km²

Arabian Peninsula is a pen/cape in Asia, covering an estimated 297,867 km². It extends across Yemen, Saudi Arabia, Oman, Kuwait, the United Arab Emirates, Qatar, Bahrain and Jordan.

The Arabian Peninsula, or simply Arabia, is a peninsula in West Asia. It accounts for the majority of the land situated on the Arabian plate. With an area of 3,237,500 km2 (1.25 million mi2), it is the world's largest peninsula—roughly comparable in size to India. Nine countries are located on the Arabian Peninsula: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates, and Yemen, as well as the southern halves of Iraq and Jordan.

Geographically, the Arabian Peninsula is bounded by Mesopotamia and the Levant to the north and northwest and surrounded by the Indian Ocean: the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman to the east and northeast; the Arabian Sea to the southeast; and the Gulf of Aden to the south, the Strait of Mandeb to the southwest, and the Red Sea to the west. Prior to the 7th century AD, Greco-Roman conceptions of "Arabia" were broader than the modern peninsula and extended into the Southern Levant, including the Sinai, the Negev, and regions of modern Jordan, as reflected in the Roman province of Arabia Petraea, whose capital was Petra.

More about Arabian Peninsula

Geography

The Arabian Peninsula is located in the continent of Asia and is bounded by (clockwise) the Persian Gulf to the north-east, the Strait of Hormuz and the Gulf of Oman to the east, the Arabian Sea to the south-east, the Gulf of Aden and the Guardafui Channel to the south, and the Bab-el-Mandeb strait to the south-west and the Red Sea to the south-west and west.

The northern portion of the peninsula transitions into the Syrian Desert with no clear borderline, although the northern boundary of the peninsula is generally considered to be the northern borders of Saudi Arabia and Kuwait, as well as the southern regions of Iraq and Jordan.

History

Prehistoric Arabia is the period of the Arabian Peninsula before any written records are known, going back to when humans first began to settle in the region, until around 1000 BC, when systematic written documentation begins to appear in the archaeological record. Stone tools from the Middle Paleolithic era along with fossils of other animals discovered at Ti's al Ghadah, in north-western Saudi Arabia, might imply that hominins migrated through a "Green Arabia" between 300,000 and 500,000 years ago.

Two-hundred-thousand-year-old stone tools were discovered at Shuaib Al-Adgham in the eastern Al-Qassim Province, which would indicate that many prehistoric sites, located along a network of rivers, had once existed in the area.

Wahiba Sands

Desert · 11,157 km²

Wahiba Sands is a desert in Asia, covering an estimated 11,157 km².

The Sharqiya Sands (Arabic: ٱلرِّمَال ٱلشَّرْقِيَّة, romanized: Ar-Rimāl Ash-Sharqiyyah, formerly known as Wahiba Sands (Arabic: رِمَال وَهِيْبَة, romanized: Rimāl Wahībah or Arabic: رَمْلَة آل وَهِيْبَة, romanized: Ramlat Āl Wahībah)) is a region of desert in Oman. The region was named for the Bani Wahiba tribe. Divided between the northern and southern governorates in the Eastern Region. The area is defined by a boundary of 180 kilometers (110 mi) north to south and 80 kilometers (50 mi) east to west, with an area of 12,500 square kilometers (4,800 sq mi). The desert has been of scientific interest since a 1986 expedition by the Royal Geographical Society documented the diversity of the terrain, the flora and fauna, noting 16,000 invertebrates as well as 200 species of other wildlife, including avifauna. They also documented 150 species of native flora.

More about Wahiba Sands

Geology

The desert was formed during the Quaternary period as a result of the forces of south-west blowing monsoon and the northern shamal trade wind, coming in from the east. Based on the types of dunes found in the area, it is divided into the high, or upper, Wahiba and low Wahiba. The upper area contains mega-ridge sand systems on a north–south line that are believed to have been formed by monsoon. The dunes of the north, formed at some point after the last regional glaciation, measure up to 100 meters (330 ft) high, with peaks accumulating in the areas just beyond the strongest wind speeds, where declining velocity wind deposited sand. The north and west boundaries of the desert are delineated by the fluvial systems Wadi Batha and Wadi Andam.

Al Hajar Mountains

Range/mtn · 943 km²

Al Hajar Mountains is a range/mtn in Asia, covering an estimated 943 km². It extends across Oman and the United Arab Emirates.

The Hajar Mountains (Arabic: جِبَال ٱلْحَجَر, romanized: Jibāl al-Ḥajar, The Rocky Mountains or The Stone Mountains) are one of the highest mountain ranges in the Arabian Peninsula, shared between northern Oman and eastern United Arab Emirates. Also known as "Oman Mountains", they separate the low coastal plain of Oman from the high desert plateau, and lie 50–100 km (31–62 miles) inland from the Gulf of Oman.

More about Al Hajar Mountains

Geography

The central section of the Hajar is the highest and wildest terrain in the country. Jabal Shams is the highest of the range, followed by Jebel Akhdar. The latter and the smaller Jebel Nakhl range are bounded on the east by the low Samail Valley (which leads northeast to Muscat).

East of Samail are the Eastern Hajar (Arabic: ٱلْحَجَر ٱلشَّرْقِي, romanized: Al-Ḥajar Ash-Sharqī), which run east (much closer to the coast) to the port city of Sur, almost at the easternmost point of Oman.

The mountains to the west of Sama'il Valley, particularly those in Musandam Peninsula and the UAE, are known as the Western Hajar (Arabic: ٱلْحَجَر ٱلْغَرْبِي, romanized: Al-Ḥajar Al-Gharbī), also known as the "Oman proper".

Geology

The Hajar Mountains extend for 700 kilometres (430 miles) through the UAE and Oman. They are located on the north-east corner of the Arabian Plate, reaching from the Musandam Peninsula through to the east coast of Oman. The range is about 100 km (62 mi) wide, with Jabal Shams being the highest peak at 3,009 m (9,872 ft) in the central region of the mountains.

Currently, the Arabian Plate is moving north relative to the Eurasian Plate at 2–3 cm (0.79–1.18 in) per year. Continental collision is occurring at the Zagros fold and thrust belt west of the Musandam Peninsula. This collisional plate boundary transitions into a subduction zone, towards the east. Here, oceanic crust of the Arabian Plate is subducted northwards beneath Eurasia, called the Makran subduction zone.

More about Musandam Peninsula

Geography

The peninsula lies to the south of the Strait of Hormuz, between the Persian Gulf and the Gulf of Oman.

It is inhabited by the Bedouin Shihuh tribe and the Iranic Kumzari people.

It is mainly governed by Oman as the Musandam Governorate with certain parts governed by the United Arab Emirates, including Ras Al Khaimah and parts of Dibba.

Land features include the Western Hajar Mountains. Since these are the northernmost of the Hajar range, they and the peninsula are referred to as Ruʾūs al-Jibāl (Arabic: رُؤُوْس ٱلْجِبَال, romanized: Capes of the Mountains). The largest wadi in Musandam is Wadi Bih, which forms the central drainage basin. The highest mountain in Musandam, and Ru'us al Jibal, is Jebel Harim.

History

In the past, the region was unstable and was repeatedly invaded by Persian empires such as the Achaemenid Empire and the Sassanian Empire. These empires then declined until the Islamic era arrived.

In the modern era, occupation of the Peninsula continued. In 1507, Afonso de Albuquerque captured key areas along the Omani coast, including Sur, Muscat, and Khasab. From then, until 1650, the Portuguese used Khasab as a supply point for the dates trade as well as a safe passage for their ships in the region. By the early 1600s, native tribes began asserting more control, and the Portuguese presence in the area dwindled.
