Which plates are separating at the East African Rift Zone?

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.

Which plates are a involved the East African Rift Valley?

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.

Which two plates are involved in the East Africa rift zone and the formation of the Read Sea?

The Red Sea Rift is a spreading center between two tectonic plates, the African Plate and the Arabian Plate.

What is happening at the East African Rift Valley?

Large crack in East African Rift is evidence of continent splitting in two. A large crack, stretching several kilometers, made a sudden appearance recently in south-western Kenya. The tear, which continues to grow, caused part of the Nairobi-Narok highway to collapse and was accompanied by seismic activity in the area.

Where is Africa splitting apart?

Scientists say a new ocean will form in Africa as the continent continues to split into two. The East African Rift system made up the western and eastern continental rifts, and stretches from the Afar region of Ethiopia down to Mozambique.

What is the most important feature of the Great Rift Valley in East Africa?

One of the most important features of the Gregory Rift is the Afar Triple Junction, found where the Horn of Africa straddles the Red Sea and the Gulf of Aden in the Arabian Sea. At the Afar Triple Junction, the Arabian plate, Nubian plate and Somali plate are all tearing away from each other.

How fast is Africa splitting apart?

The three plates are separating at different speeds. The Arabian plate is moving away from Africa at a rate of about 1 inch per year, while the two African plates are separating even slower, between half an inch to 0.2 inches per year, according to Macdonald.

Why has the East African Rift Valley formed what type of plate margin is there?

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’.

What will eventually happen if a Rift Valley continues to pull apart?

If these two rift zones continue they will break apart the crustal plates they are located on and will create new plates. Sea water will flood the rift valleys and they will eventually become seas like the Red Sea.

What causes the tectonic plates to move?

The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.

What if the African continent broke apart?

As the plates continue to pull away from each other, the rift valley will sink deeper and deeper, and water from the Red Sea will flood in to create a new ocean. Africa will become a lot smaller, as parts of southern Ethiopia and Somalia will drift off to form a new island.

What countries does the Rift Valley go through?

The Rift Valley consists of a group of independent interior basins, extending from Djibouti in the north to Tanzania in the south, nearly half being located in Ethiopia.

Name of basin Total area of basin Area in the country
Sudan 16 441
Uganda 4 514
Kenya 102 452
Southern lakes: 178 800

What will happen if the East African rift continues?

If these motions continue, plate models (mentioned below) suggest that Africa would rotate clockwise and eventually crash into Europe in 50 Ma in the future. The rift is growing at a rate of one inch per year through the upwelling of magma underneath the continental crust (see Fig.

Why is there no earthquakes in Africa?

Parts of Africa (notably West Africa) have very few earthquakes. But this is true of most continents. … This is primarily because there are no major subduction zones in Africa and subduction zones seem to be responsible for the largest types of earthquakes (so-called “megathrust” earthquakes ).

Why is Africa divided?

This conference was called by German Chancellor Bismarck to settle how European countries would claim colonial land in Africa and to avoid a war among European nations over African territory. … All the major European States were invited to the conference.

Why is Africa called the mother continent?

Africa is sometimes nicknamed the “Mother Continent” due to its being the oldest inhabited continent on Earth. Humans and human ancestors have lived in Africa for more than 5 million years.
