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.

Middle East

The Middle East (also called the Mid East) is a transcontinental region centered on Western Asia and Egypt. The corresponding adjective is Middle-Eastern and the derived noun is Middle-Easterner. Formerly, the Eurocentric synonym Near East (as opposed to Far East) was commonly used. Arabs, Azeris, Kurds, Persians, and Turks constitute the largest ethnic groups in the region by population, while Armenians, Assyrians, Circassians, Copts, Druze, Jews, Maronites, Somalis, and other ethnic and ethno-religious groups form significant minorities.

The History of the Middle East dates back to ancient times, with the (geo-political) importance of the region being recognized for millennia. Several major religions have their origins in the Middle East, including Judaism, Christianity, and Islam; the Baha'i faith, Mandaeism, Unitarian Druze, and numerous other belief systems were also established within the region. The Middle East generally has a hot, arid climate, with several major rivers providing irrigation to support agriculture in limited areas such as the Nile Delta in Egypt, the Tigris and Euphrates watersheds of Mesopotamia, and most of what is known as the Fertile Crescent. Most of the countries that border the Persian Gulf have vast reserves of crude oil, with the dictatorships of the Arabian Peninsula in particular benefiting from petroleum exports. In modern times the Middle East remains a strategically, economically, politically, culturally and religiously sensitive region.

Iran

Iran (/aɪˈræn/ or ⁱ/ɪˈrɑːn/;Persian: Irān – ایران‎‎ [ʔiːˈɾɒːn]), also known as Persia (/ˈpɜːrʒə/ or /ˈpɜːrʃə/), officially the Islamic Republic of Iran (جمهوری اسلامی ایران – Jomhuri ye Eslāmi ye Irān [d͡ʒomhuːˌɾije eslɒːˌmije ʔiːˈɾɒːn]), is a country in Western Asia. It is bordered to the northwest by Armenia, the de facto Nagorno-Karabakh, and Azerbaijan; with Kazakhstan and Russia across the Caspian Sea; to the northeast by Turkmenistan; to the east by Afghanistan and Pakistan; to the south by the Persian Gulf and the Gulf of Oman; and to the west by Turkey and Iraq. Comprising a land area of 1,648,195 km² (636,372 sq mi), it is the second-largest country in the Middle East and the 18th-largest in the world. With 78.4 million inhabitants, Iran is the world's 17th-most-populous country. It is the only country that has both a Caspian Sea and an Indian Ocean coastline. Iran has long been of geostrategic importance because of its central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz.

Arabian Peninsula

Arabian Peninsula, simplified Arabia (Arabic: الجزيرة العربية‎ al-jazīra al-ʿarabiyya, « Arabian island ») is a peninsula of Western Asia situated north-east of Africa on the Arabian plate. From a geological perspective, it is considered a subcontinent of Asia.

It is the largest peninsula in the world, at 3,237,500 km² (1,250,000 sq mi). The Arabian Peninsula consists of the countries Yemen, Oman, Qatar, Bahrain, Kuwait, Saudi Arabia and the United Arab Emirates as well as parts of southern Iraq and Jordan. The peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west, the Persian Gulf to the northeast, the Levant to the north and the Indian Ocean to the southeast. The Arabian Peninsula plays a critical geopolitical role in the Middle East and Arab world due to its vast reserves of oil and natural gas.

Before the modern era, it was divided into four distinct regions: Hejaz, Najd, Southern Arabia and Eastern Arabia. Hejaz and Najd make up most of Saudi Arabia. Southern Arabia consists of Yemen and some parts of Saudi Arabia and Oman (Dhofar). Eastern Arabia consists of the entire coastal strip of the Arab side of the Persian Gulf (the Khaleej).

Ring of Fire

The Ring of Fire is an area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. It has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes. The Ring of Fire is sometimes called the circum-Pacific belt.

About 90% of the world's earthquakes and 81% of the world's largest earthquakes occur along the Ring of Fire. The next most seismically active region (5–6% of earthquakes and 17% of the world's largest earthquakes) is the Alpide belt, which extends from Java to the northern Atlantic Ocean via the Himalayas and southern Europe.

All but 3 of the world's 25 largest volcanic eruptions of the last 11,700 years occurred at volcanoes in the Ring of Fire.
