Jeddah

Jeddah (sometimes spelled Jiddah or Jedda ; English pronunciation: /ˈdʒɛdə/; Arabic: جدة‎ Jiddah or Jaddah, IPA: [ˈdʒedda, ˈdʒidda]) is a city in the Hijaz Tihamah region on the coast of the Red Sea and is the major urban center of western Saudi Arabia. It is the largest city in Makkah Province, the largest sea port on the Red Sea, and the second-largest city in Saudi Arabia after the capital city, Riyadh. With a population currently at 3.4 million people, Jeddah is an important commercial hub in Saudi Arabia.

Jeddah is the principal gateway to Mecca, Islam's holiest city, which able-bodied Muslims are required to visit at least once in their lifetime. It is also a gateway to Medina, the second holiest place in Islam.

Economically, Jeddah is focusing on further developing capital investment in scientific and engineering leadership within Saudi Arabia, and the Middle East. Jeddah was independently ranked fourth in the Africa – Mid-East region in terms of innovation in 2009 in the Innovation Cities Index.

Saudi Arabia

Saudi Arabia (ⁱ/ˌsɔːdiː əˈreɪbiə/, ⁱ/ˌsaʊ-/), officially known as the Kingdom of Saudi Arabia (KSA), is an Arab state in Western Asia constituting the bulk of the Arabian Peninsula. With a land area of approximately 2,150,000 km² (830,000 sq mi), Saudi Arabia is geographically the second-largest state in the Arab world after Algeria. Saudi Arabia is bordered by Jordan and Iraq to the north, Kuwait to the northeast, Qatar, Bahrain, and the United Arab Emirates to the east, Oman to the southeast, and Yemen to the south. It is the only nation with both a Red Sea coast and a Persian Gulf coast, and most of its terrain consists of arid inhospitable desert or barren landforms.

The area of modern-day Saudi Arabia formerly consisted of four distinct regions: Hejaz, Najd, and parts of Eastern Arabia (Al-Ahsa) and Southern Arabia ('Asir). The Kingdom of Saudi Arabia was founded in 1932 by Ibn Saud. He united the four regions into a single state through a series of conquests beginning in 1902 with the capture of Riyadh, the ancestral home of his family, the House of Saud. The country has since been an absolute monarchy, effectively a hereditary dictatorship governed along Islamic lines. The ultra-conservative Wahhabism religious movement within Sunni Islam has been called "the predominant feature of Saudi culture", with its global spreading largely financed by the oil and gas trade. Saudi Arabia is sometimes called "the Land of the Two Holy Mosques" in reference to Al-Masjid al-Haram (in Mecca), and Al-Masjid an-Nabawi (in Medina), the two holiest places in Islam. The Kingdom has a total population of 28.7 million, of which 20 million are Saudi nationals and 8 million are foreigners.

Red Sea

The Red Sea (also the Erythraean Sea) is a seawater inlet of the Indian Ocean, lying between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb strait and the Gulf of Aden. In the north, there is the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). The Red Sea is a Global 200 ecoregion. The sea is underlain by the Red Sea Rift which is part of the Great Rift Valley.

The Red Sea has a surface area of roughly 438,000 km² (169,100 mi²). It is about 2250 km (1398 mi) long and, at its widest point, 355 km (220.6 mi) wide. It has a maximum depth of 2211 m (7254 ft) in the central median trench, and an average depth of 490 m (1,608 ft). However, there are also extensive shallow shelves, noted for their marine life and corals. The sea is the habitat of over 1,000 invertebrate species, and 200 soft and hard corals. It is the world's northernmost tropical sea.
