What is the East African Rift is an example of a blank?

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.

What is the East African Rift an example of?

The East African Rift Valley is an example of a divergent boundary in an area of continental crust. It is one the geologic wonders of the world, a place where the earth’s tectonic forces are presently trying to create new plates by splitting apart old ones.

What is the East African Rift Valley known for?

The most well-known rift valley on Earth is probably the so-called “Great Rift Valley System” which stretches from the Middle East in the north to Mozambique in the south. The area is geologically active, and features volcanoes, hot springs, geysers, and frequent earthquakes.

How is the East African Rift Valley formed?

The East African Rift Valley, as the region is known, formed where the Somalian and Nubian plates are pulling away from the Arabian Plate. The eastern branch of the rift passes through Ethiopia and Kenya, and the western branch forms a giant arc from Uganda to Malawi.

What is the rift in Africa called?

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.

Why is the East African Rift rifting?

Here the eastern portion of Africa, the Somalian plate, is pulling away from the rest of the continent, that comprises the Nubian plate. … The Nubian and Somalian plates are also separating from the Arabian plate in the north, thus creating a ‘Y’ shaped rifting system.

What constitutes a rift zone like the one in Eastern Africa?

A narrow zone, the rift is a developing divergent tectonic plate boundary where the African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate, at a rate of 6–7 mm (0.24–0.28 in) per year.

What is the example of rift valley?

Continental rifts are potential places where new oceans are expected to form. Examples of rift valleys: 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.

Which river of India is an example of rift valley?

It is one of the rivers in India that flows in a rift valley, bordered by the Satpura and Vindhya ranges. As a rift valley river, the Narmada does not form a delta; Rift valley rivers form estuaries. The other rivers which flow through rift valley include Damodar River in Chota Nagpur Plateau and Tapti.

Where is the East African Rift located?

The East African Rift Valley stretches over 3,000km from the Gulf of Aden in the north towards Zimbabwe in the south, splitting the African plate into two unequal parts: the Somali and Nubian plates.

When was the African rift valley formed?

It included what today is called the Lebanese section of the Dead Sea Transform, the Jordan Rift Valley, Red Sea Rift and the East African Rift. These rifts and faults were formed 35 million years ago.

How were the African rift lakes formed?

The East African rifts attained their present form mainly as a result of earth movements during the Pleistocene Epoch (about 2,600,000 to 11,700 years ago), and the lakes must have been formed after the landscapes in which they are set.

What two plates are involved in the East African Rift?

Throughout the East African Rift, the continent of Africa is splitting in two. The African plate, sometimes called the Nubian plate, carries most of the continent, while the smaller Somali plate carries Horn of Africa. The two major rift valley systems of the East African Rift are the Gregory Rift and the Western Rift.

What is a rift system?

In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. … Major rifts occur along the central axis of most mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates.

What does rift mean in science?

rift 1. / (rɪft) / noun. a gap or space made by cleaving or splitting; fissure. geology a long narrow zone of faulting resulting from tensional stress in the earth’s crust.
