Summit
–
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. Mathematically, a summit is a maximum in elevation. The topographic terms acme, apex, peak, and zenith are synonymous, the UIAA definition is that a summit is independent if it has a prominence of 30 metres or more, it is a mountain if it has a prominence of at least 300 metres. This can be summarised as follows, A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top, Summit may also refer to the highest point along a line, trail, or route. In many parts of the western United States, the term refers to the highest point along a road, highway. For example, the highest point along Interstate 80 in California is referred to as Donner Summit while the highest point on Interstate 5 is Siskiyou Mountain Summit, geoid Hill List of highest mountains Maxima and minima Nadir Summit accordance Peak finder

Saudi Arabia
–
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 separated from Israel and Egypt by the Gulf of Aqaba and it is the only nation with both a Red Sea coast and a Persian Gulf coast and most of its terrain consists of arid desert and mountains. The area of modern-day Saudi Arabia formerly consisted of four regions, Hejaz, Najd and parts of Eastern Arabia. The Kingdom of Saudi Arabia was founded in 1932 by Ibn Saud and 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. Saudi Arabia has since been a monarchy, effectively a hereditary dictatorship governed along Islamic lines. The ultraconservative Wahhabi religious movement within Sunni Islam has been called the predominant feature of Saudi culture, with its global spread 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 and Al-Masjid an-Nabawi, the state has a total population of 28.7 million, of which 20 million are Saudi nationals and 8 million are foreigners. The states official language is Arabic, petroleum was discovered on 3 March 1938 and followed up by several other finds in the Eastern Province. Saudi Arabia has since become the worlds largest oil producer and exporter, controlling the second largest oil reserves. The kingdom is categorized as a World Bank high-income economy with a high Human Development Index and is the only Arab country to be part of the G-20 major economies. However, the economy of Saudi Arabia is the least diversified in the Gulf Cooperation Council, the state has attracted criticism for its treatment of women and use of capital punishment. Saudi Arabia is an autocracy, has the fourth highest military expenditure in the world. Saudi Arabia is considered a regional and middle power, in addition to the GCC, it is an active member of the Organisation of Islamic Cooperation and OPEC. Following the unification of the Hejaz and Nejd kingdoms, the new state was named al-Mamlakah al-ʻArabīyah as-Suʻūdīyah by royal decree on 23 September 1932 by its founder, Abdulaziz Al Saud. Although this is translated as the Kingdom of Saudi Arabia in English it literally means the Saudi Arab kingdom. Its inclusion expresses the view that the country is the possession of the royal family. Al Saud is an Arabic name formed by adding the word Al, meaning family of or House of, in the case of the Al Saud, this is the father of the dynastys 18th century founder, Muhammad bin Saud. There is evidence that human habitation in the Arabian Peninsula dates back to about 125,000 years ago

Hejaz
–
The Hejaz, also Al-Hijaz, is a region in the west of present-day Saudi Arabia. The region is so called as it separates the land of the Najd in the east from the land of Tihamah in the west and it is also known as the Western Province. It is bordered on the west by the Red Sea, on the north by Jordan, on the east by the Najd and its main city is Jeddah, but it is probably better known for the Islamic holy cities of Mecca and Medina. As the site of Islams holiest places, the Hejaz has significance in the Arab, historically, the Hejaz has always seen itself as separate from the rest of Saudi Arabia. The Hejaz is the most populated region in Saudi Arabia,35 % of all Saudis live in Hejaz, hejazi Arabic is the most widely spoken dialect in the region. Saudi Hejazis are of diverse origins. The Hejaz is the most cosmopolitan region in the Arabian Peninsula, people of Hejaz have the most strongly articulated identity of any regional grouping in Saudi Arabia. Their place of origin alienates them from the Saudi state, which invokes different narratives of the history of the Arabian Peninsula, thus, Hejazis experienced tensions with people of Najd. One or possibly two megalithic dolmen have been found in Al-Hijaz, the Hejaz includes both the Mahd adh-Dhahab and a water source, now dried out, that used to flow 600 miles north east to the Persian Gulf via the Wadi Al-Rummah and Wadi Al-Batin system. Archaeological research led by of Boston University and the University of Qassim indicates that the system was active in 8000 BCE. The northern part of the Hejaz was part of the Roman province of Arabia Petraea, Saudi Arabias first World Heritage Site that was recognized by the United Nations Educational, Scientific and Cultural Organization is that of Al-Hjir. The name Al-Hijr occurs in the Qur’an, and the site is known for having structures carved into rocks, construction of the structures is credited to the people of Thamud. Despite their rather Polytheistic nature, a member of folk was a Monotheistic preacher called Salih. After the disappearance of Thamud from Mada’in Saleh, it came under the influence of people, such as the Nabataeans. Later, it would lie in a used by Muslim Pilgrims going to Mecca. According to Islamic sources, the civilization of Mecca started after Ibrahim brought his son Isma‘il and wife Hajar here and it was during such an occasion that Muhammad met some Medinans who would allow him to migrate to Medina, to escape persecution by his opponents in Mecca. Given that he had followers and enemies here, a number of battles or expeditions were carried out in this area. They involved both Meccan companions, such as Hamzah ibn ‘Abdul-Muttalib, Ubaydah ibn al-Harith and Sad ibn Abi Waqqas, the Hijaz fell under Muhammads influence as he emerged victorious over his opponents, and was thus a part of his empire

Mountain range
–
A mountain range is a geographic area containing numerous geologically related mountains. A mountain system or system of ranges, sometimes is used to combine several geological features that are geographically related. Mountain ranges are usually segmented by highlands or mountain passes and valleys, individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, most geologically young mountain ranges on the Earths land surface are associated with either the Pacific Ring of Fire or the Alpide Belt. The Andes is 7,000 kilometres long and is considered the worlds longest mountain system. The Alpide belt includes Indonesia and southeast Asia, through the Himalaya, the belt also includes other European and Asian mountain ranges. The Himalayas contain the highest mountains in the world, including Mount Everest, mountain ranges outside of these two systems include the Arctic Cordillera, the Urals, the Appalachians, the Scandinavian Mountains, the Altai Mountains and the Hijaz Mountains. If the definition of a range is stretched to include underwater mountains. The mountain systems of the earth are characterized by a tree structure, the sub-range relationship is often expressed as a parent-child relationship. For example, the White Mountains of New Hampshire and the Blue Ridge Mountains are sub-ranges of the Appalachian Mountains, equivalently, the Appalachians are the parent of the White Mountains and Blue Ridge Mountains, and the White Mountains and the Blue Ridge Mountains are children of the Appalachians. The position of mountains influences climate, such as rain or snow, when air masses move up and over mountains, the air cools producing orographic precipitation. As the air descends on the side, it warms again and is drier. Often, a shadow will affect the leeward side of a range. Mountain ranges are constantly subjected to forces which work to tear them down. Erosion is at work while the mountains are being uplifted and long after until the mountains are reduced to low hills, rivers are traditionally believed to be the principle erosive factor on mountain ranges, with their ability of bedrock incision and sediment transport. The rugged topography of a range is the product of erosion. The basins adjacent to a mountain range are filled with sediments which are buried and turned into sedimentary rock. The early Cenozoic uplift of the Rocky Mountains of Colorado provides an example and this mass of rock was removed as the range was actively undergoing uplift

Red Sea
–
The Red 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, to the north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez. 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 an area of roughly 438,000 km2, is about 2250 km long and. It has a depth of 2211 m in the central median trench. However, there are also extensive shallow shelves, noted for their marine life, the sea is the habitat of over 1,000 invertebrate species, and 200 soft and hard corals. It is the worlds northernmost tropical sea, the International Hydrographic Organization defines the limits of the Red Sea as follows, On the North. The Southern limits of the Gulfs of Suez and Aqaba, a line joining Husn Murad and Ras Siyyan. Red Sea is a translation of the Greek Erythra Thalassa, Latin Mare Rubrum, Arabic, البحر الأحمر. Al-Baḥr Al-Aḥmar, Somali Badda Cas and Tigrinya Qeyyiḥ bāḥrī, the name of the sea may signify the seasonal blooms of the red-coloured Trichodesmium erythraeum near the waters surface. A theory favored by modern scholars is that the name red is referring to the direction south. The basis of this theory is that some Asiatic languages used color words to refer to the cardinal directions, herodotus on one occasion uses Red Sea and Southern Sea interchangeably. Historically, it was known to western geographers as Mare Mecca. Some ancient geographers called the Red Sea the Arabian Gulf or Gulf of Arabia. C, in that version, the Yam Suph is translated as Erythra Thalassa. The Red Sea is one of four seas named in English after common color terms — the others being the Black Sea, the White Sea and the Yellow Sea. The direct rendition of the Greek Erythra thalassa in Latin as Mare Erythraeum refers to the part of the Indian Ocean. The earliest known exploration of the Red Sea was conducted by ancient Egyptians, one such expedition took place around 2500 BC, and another around 1500 BC. Both involved long voyages down the Red Sea, historically, scholars argued whether these trips were possible

Arabian Peninsula
–
The Arabian Peninsula, simplified Arabia is a peninsula of Western Asia situated northeast of Africa on the Arabian plate. From a geological perspective, it is considered a subcontinent of Asia and it is the largest peninsula in the world, at 3,237,500 km2. The Arabian Peninsula consists of the countries Yemen, Oman, Qatar, Bahrain, Kuwait, Saudi Arabia, the Arabian Peninsula plays a critical geopolitical role in the Middle East and the Arab world due to its vast reserves of oil and natural gas. Before the modern era, it was divided into four regions, Hejaz, Najd, Southern Arabia. Hejaz and Najd make up most of Saudi Arabia, Southern Arabia consists of Yemen and some parts of Saudi Arabia and Oman. Eastern Arabia consists of the coastal strip of the Persian Gulf. The most prominent feature of the peninsula is desert, but in the southwest there are mountain ranges, harrat ash Shaam is a large volcanic field that extends from the northwestern Arabian Peninsula into Jordan and southern Syria. The peninsulas constituent countries are Kuwait, Bahrain, Qatar, the island nation of Bahrain lies off the east coast of the peninsula. Six countries form the Gulf Cooperation Council, however, this is a disputed term. The Kingdom of Saudi Arabia covers the part of the peninsula. The majority of the population of the live in Saudi Arabia. The peninsula contains the worlds largest reserves of oil, Saudi Arabia and the UAE are economically the wealthiest in the region. Qatar, a peninsula in the Persian Gulf on the larger peninsula, is home of the Arabic-language television station Al Jazeera. Kuwait, on the border with Iraq, is an important country strategically, though historically lightly populated, political Arabia is noted for a high population growth rate - as the result of both very strong inflows of migrant labor as well as sustained high birth rates. The population tends to be young and heavily skewed gender ratio dominated by males. In many states, the number of South Asians exceeds that of the local citizenry, the four smallest states, which have their entire coastlines on the Persian Gulf, exhibit the worlds most extreme population growth, roughly tripling every 20 years. In 2014, the population of the Arabian Peninsula was 77,983,936. Listed here are the human Y-chromosome DNA haplogroups in Arabia Haplogroup J is the most abundant component in the Arabian peninsula and its two main subclades, show opposite latitudinal gradients in the Middle East
