Mount Roraima is the highest of the Pakaraima chain of tepuis (table-top mountain) or plateaux in South America. It is located at the junction of Venezuela, Brazil, and Guyana. A characteristic large flat-topped mountain surrounded by cliffs 400 to 1,000 meters high. The highest point of Mount Roraima is located on the southern edge of the cliff at an altitude of 2,810 meters in Venezuela, and another protrusion at an altitude of 2,772 meters at the junction of the three countries in the north of the plateau is the highest point in Guyana. The name of Mount Roraima came from the native Pemon people. Roroi in the Pemon language means “blue-green”, and ma means “great”.

Leaching caused by intense rainfall has shaped the peculiar topography of the summit, and the geographical isolation of Mount Roraima has made it home to much endemic flora and fauna. Western exploration of Mount Roraima did not begin until the 19th century when it was first climbed by a British expedition in 1884. Yet despite subsequent expeditions, its flora and geology remain largely unknown. The privileged setting and relatively easy access and climbing conditions on the south side of the cliffs make Mount Roraima one of the most popular destinations for hikers.

Mount Roraima is located in the northern part of South America, the Pacarema Mountains in the eastern part of the Guyana Plateau, Brazil in the east accounting for 5% of its area, Guyana in the north accounting for 10%, and Venezuela in the south and west accounting for 85%. Access to Mount Roraima from the Venezuelan side is close to the road and relatively easy; however, for both Brazil and Guyana the area is completely isolated and can only be reached by a few days of forest hikes or small local airstrip.

Mount Roraima is a flat-topped mountain, typical of the Guyana Shield, with an elevation of about 1,200 meters in the southeast and only about 600 meters in the northwest. The south, southeast, east, northeast, and northwest faces are all formed by straight cliffs up to about 1,000 meters high. At the southern end of the mountain, part of the cliff has collapsed, forming a spectacular natural boulder. The base of the cliff is surrounded by steep slopes to the south and east, and the north and west sides form river valleys leading to the summit.

The top of Mount Roraima has a length of more than 10 kilometers, a maximum width of 5 kilometers, an area of ​​about 33 to 50 square kilometers, an altitude of more than 2200 meters, and an average altitude of 2600–2700 meters. The plateau is a pseudo-karst surface etched by heavy rainfall. The highest point is 2810 meters above sea level, located at the southern end of the plateau and the highest point in the state of Bolivar, 8.25 kilometers north of the summit is another high point with an altitude of 2,772 meters, which is the highest point in Guyana. In the northern part of the plateau is the landmark of the border between Brazil, Venezuela, and Guyana, with an altitude of 2734 meters.

Due to its high altitude and proximity to the equator, Mount Roraima has a constant average annual temperature between 20 and 22 °C and annual rainfall of more than 1,500 mm, with 1,800 to 3,000 mm in parts of the rainy season from April to November. The climatic conditions at the top of the mountain differ significantly from its base, the high cloudiness in the region is associated with the prevailing northeasterly and southeasterly winds, and the relative humidity of the air remains between 75% and 85%.

Tanzania, officially the United Republic of Tanzania, is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa’s highest mountain, is in northeastern Tanzania.

Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus Homo are found near Lake Olduvai. Following the rise of Homo erectus 1.8 million years ago, humanity spread all over the Old World, and later in the New World and Australia under the species Homo sapiens. H. sapiens also overtook Africa and absorbed the older species of humanity.

Later in the Stone and Bronze Age, prehistoric migrations into Tanzania included Southern Cushitic speakers who moved south from present-day Ethiopia; Eastern Cushitic people who moved into Tanzania from north of Lake Turkana about 2,000 and 4,000 years ago; and the Southern Nilotes, including the Datoog, who originated from the present-day South Sudan–Ethiopia border region between 2,900 and 2,400 years ago. These movements took place at about the same time as the settlement of the Mashariki Bantu from West Africa in the Lake Victoria and Lake Tanganyika areas. They subsequently migrated across the rest of Tanzania between 2,300 and 1,700 years ago.

German rule began in mainland Tanzania during the late 19th century when Germany formed German East Africa. This was followed by British rule after World War I. The mainland was governed as Tanganyika, with the Zanzibar Archipelago remaining a separate colonial jurisdiction. Following their respective independence in 1961 and 1963, the two entities merged in 1964 to form the United Republic of Tanzania. The countries had joined the British Commonwealth in 1961 and Tanzania is still a member of the Commonwealth as one republic.

The United Nations estimated Tanzania’s population at 63.59 million, which is slightly smaller than South Africa and makes it the second-most populous country located entirely south of the Equator. The population is composed of about 120 ethnic, linguistic, and religious groups. The sovereign state of Tanzania is a presidential constitutional republic and since 1996 its official capital city has been Dodoma where the president’s office, the National Assembly, and all government ministries are located. Dar es Salaam, the former capital, retains most government offices and is the country’s largest city, principal port, and leading commercial center. Tanzania is a de facto one-party state with the democratic socialist Chama Cha Mapinduzi party in power.

Tanzania is mountainous and densely forested in the northeast, where Mount Kilimanjaro is located. Three of Africa’s Great Lakes are partly within Tanzania. To the north and west lie Lake Victoria, Africa’s largest lake, and Lake Tanganyika, the continent’s deepest lake, known for its unique species of fish. To the south lies Lake Malawi. The eastern shore is hot and humid, with the Zanzibar Archipelago just offshore. The Menai Bay Conservation Area is Zanzibar’s largest marine protected area. The Kalambo Falls, located on the Kalambo River at the Zambian border, is the second-highest uninterrupted waterfall in Africa.

Christianity is the largest religion in Tanzania, but there are also substantial Muslim and Animist minorities. Over 100 different languages are spoken in Tanzania, making it the most linguistically diverse country in East Africa. The country does not have a de jure official language, although the national language is Swahili. Swahili is used in parliamentary debate, in the lower courts, and as a medium of instruction in primary school. English is used in foreign trade, in diplomacy, in higher courts, and as a medium of instruction in secondary and higher education; although the Tanzanian government is planning to discontinue English as the primary language of instruction, it will be available as an optional course. Approximately 10% of Tanzanians speak Swahili as a first language, and up to 90% speak it as a second language. Wikipedia
