What is the East African Rift Valley an example of?

How do you describe the Great East African Rift Valley?

East African Rift System, also called Afro-Arabian Rift Valley, one of the most extensive rifts on Earth’s surface, extending from Jordan in southwestern Asia southward through eastern Africa to Mozambique. The system is some 4,000 miles (6,400 km) long and averages 30–40 miles (48–64 km) wide.

What does the valley of the East African Rift mean?

Today, the term is most often used to refer to the valley of the East African Rift, the divergent plate boundary which extends from the Afar Triple Junction southward across eastern Africa, and is in the process of splitting the African Plate into two new separate plates.

How does a rift valley occur?

A rift valley is a lowland region that forms where Earth’s tectonic plates move apart, or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading. Two arms of the triple junction can split to form an entire ocean.

What’s an example of a Rift Valley?

Very few active rift valleys are found on continental lithosphere. The East African Rift, the Baikal Rift Valley, the West Antarctic Rift, and the Rio Grande Rift are Earth’s major active continental rift valleys. The East African Rift is part of the “Great Rift Valley” system discussed below.

How is the Great Rift Valley used in geology?

While the name continues in some usages, it is rarely used in geology as it is considered an imprecise merging of separate though related rift and fault systems.

Who was the first person to discover the Rift Valley?

Following on the mid- to late-19th-century work of dozens of explorers including the famous David Livingstone, the concept of an East African rift fracture was established by Austrian geologist Eduard Suess, and named the Great Rift Valley of East Africa in 1896 by British geologist John Walter Gregory.

Are there volcanoes in the East African Rift?

East Africa with active volcanoes (red triangles) and the Afar Triangle (shaded, center)—a triple junction where three plates are pulling away from one another. The East African rift has two branches, the Western Rift Valley and the Eastern Rift Valley.

Is the East African Rift Valley is an example of continental rifting?

Types of Rifting:- The Afar triangle of the East African Rift (EAR) system is an example of a triple junction. These first two rifts separate Africa from Arabia while the third is splitting the continental crust of north-eastern Africa. This image shows the East African rift valley system.

What is the East African Rift Valley an example of?

The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa.
