![]() Africa and Asia are now linked via the Sinai Peninsula's triangle. The Red Sea was formed when the Indian Ocean swamped the rift valley between the continents. The Arabian and African plates drifted apart as a result of seafloor spreading. The Arabian Peninsula has formerly connected to Africa millions of years ago. The Red Sea Rift is associated with the Jordan Rift Valley to the south. John Walter Gregory, an explorer, gave it his name. The valley's breadth ranges from thirty to one hundred kilometres, and its depth ranges from a few hundred to thousands of metres. The Great Rift Valley is a 5,000-kilometre-long geological and topographical feature that stretches from northern Syria in Southwest Asia to central Mozambique in East Africa. The Great Rift Valley in the eastern Democratic Republic of Congo is home to one of the world's most active and deadly volcanoes. The Albertine Rift, commonly known as the Western Rift, has some of the world's deepest lakes. The Eastern Rift and the Western Rift split the valley in eastern Africa. ![]() The Great Rift Valley, which split the earlier Ethiopian highlands into two halves, continues the fault in a southwesterly path. The Beqaa Valley in Lebanon is formed by the northernmost portion of the Rift. ![]() The best example of a Divergent Boundary is the Great Rift Valley. The Jordan Rift Valley spans from the Golan Heights, near Israel's border with Syria and Lebanon, to the Dead Sea, and finally to the Gulf of Aqaba, which connects the Sinai Peninsula and the Arabian Peninsula. The Jordan Rift Valley is located in the system's northern reaches. The rift valleys in the "system" are all connected, although they aren't all part of the same unit. The Great Rift Valley, on the other hand, is a cultural concept rather than a scientific one today. Volcanoes, hot springs, geysers, and earthquakes abound in this geologically active region. The "Great Rift Valley System," which runs from the Middle East to Mozambique in the south, is possibly the most well-known rift valley on the planet. Gregory identified the GRV as the Afro-Arabian rift system in 1921, describing it as a sequence of graben basins that includes the valleys of the Red and Dead Seas in western Asia. The biggest active continental rift valleys on Earth are the East African Rift, the Baikal Rift Valley, the West Antarctic Rift, and the Rio Grande Rift.įollowing on the mid-to-late-19th-century, the efforts of dozens of explorers, including the legendary David Livingstone, Austrian geologist Eduard Suess devised the concept of an East African rift fracture, which was named the Great Rift Valley of East Africa by British geologist John Walter Gregory in 1896. The San Andreas fault is a transform fault that separates the Pacific plate's northward migration from the North American plate's southward movement. The Salton Trough is a rift valley produced in part by the San Andreas Fault that runs through the states of California and Baja California in Mexico. ![]() ![]() Transform faults, where tectonic plates grind against each other, can also generate rift valleys. Another theory is that the centre block is driven down by the over-thrust peripheral masses in a compressional rift bounded by reversal faults. When two large blocks of the earth's crust separate, the rift valleys are formed. On a divergent plate boundary, it is like a crustal expansion or spreading apart of the surface forms a rift valley, which is then further deepened by erosion pressures. Rift valleys are distinct from the river and glacial valleys as they are formed by tectonic action rather than erosion.Ī rift valley is formed due to the subsidence of the floor of a river valley. Rift valleys can be found both on land and at the bottom of the ocean, where they are generated by seafloor spreading. A rift valley can be defined as a long, narrow valley formed by the depression of a block of the earth's crust between two parallel faults or sets of faults. ![]()
