What Type Of Plate Boundary Is The East African Rift Valley?

The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa. Here the eastern portion of Africa, the Somalian plate, is pulling away from the rest of the continent, that comprises the Nubian plate.

What plates formed the East African Rift Valley?

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 type of plate boundary is the Great Rift Valley? 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.

Is the African Rift Valley constructive plate boundary?

Landforms associated with constructive plate boundaries rift valleys – such as the East African Rift Valley where the African plate is tearing itself apart.

What kind of plate boundary is east Africa becoming?

The rifting then extends southwards where the African Plate is itself becoming stretched along the line of the East African Rift Valley and is splitting to form two new plates; the Nubian and Somalian Plates. The point in the Afar region where the boundaries of all three plates meet is called a Triple Junction.

Which countries does the rift valley pass through?

Why is the East African rift rifting?

The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa. … The Nubian and Somalian plates are also separating from the Arabian plate in the north, thus creating a ‘Y’ shaped rifting system. These plates intersect in the Afar region of Ethiopia at what is known as a ‘triple junction’.

How is a rift valley formed?

A rift valley is a lowland region formed by the interaction of Earth’s tectonic plates. … 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.

Is the Japan island arc a divergent boundary?

Japan has been situated in the convergent plate boundary during long geohistorical ages. This means that the Japanese islands are built under the subduction tectonics.

Is the Great Rift Valley a divergent boundary?

Great Rift Valley (The Best Example of a Divergent Boundary) … In a southwest direction, the fault continues as the Great Rift Valley, which split the older Ethiopian highlands into two halves. In eastern Africa, the valley divides into the Eastern Rift and the Western Rift.

What are divergent boundaries?

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.

Is Great Rift Valley of East Africa divergent?

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 another name for a constructive plate boundary?

A constructive plate boundary, sometimes called a divergent plate margin, occurs when plates move apart. Volcanoes are formed as magma wells up to fill the gap, and eventually new crust is formed.

What type of boundary is the African plate?

Boundaries. The western edge of the African Plate is a divergent boundary with the North American Plate to the north and the South American Plate to the south which forms the central and southern part of the Mid-Atlantic Ridge.

Is Africa really splitting apart?

Scientists say a new ocean will form in Africa as the continent continues to split into two. … It is an active continental rift that began millions of years ago, splitting at 7mm annually.

Is Africa continent breaking apart?

Scientists say a new ocean is being born. New satellite measurements are offering valuable tools to study the tectonic rift in one of the most geologically unique spots on the planet.
