Best answer: What type of fault is the East African Rift?

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.

Which type of fault would be most common at the East African Rift?

Landscapes in the rift valley can appear confusing. The most striking features in this view are the numerous, nearly parallel, linear fault lines that occupy the floor of the valley.

What kind of tectonic motion caused the East African Rift?

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.

Is the East African Rift convergent?

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 caused the African Rift Valley?

Millions of years ago, the Arabian Peninsula was connected to Africa. Seafloor spreading caused the Arabian and African plates to rift apart. The Indian Ocean flooded the rift valley between the continents, creating the Red Sea. … South of the Red Sea Rift lies the massive, complex East African Rift.

What is the East African Rift an example of?

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.

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.

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.

What if 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.

Are Saudi Arabia and Africa moving apart?

Red Sea rifting began in the Eocene, but the separation of Africa and Arabia occurred approximately 25 million years ago in the Oligocene, and since then the Arabian Plate has been slowly moving toward the Eurasian Plate.

What African countries does the Great Rift Valley pass 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

Where is the East African Rift Valley located?

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 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.

How many volcanoes are in the East African Rift Valley?

More than 100 young volcanoes – that have had activity within about 10,000 years – dot the landscape of the East African Rift – an area that runs for more than 3000 kilometres from Djibouti and Eritrea, down through Ethiopia, Kenya, Uganda and Rwanda to the Democratic Republic of Congo and Tanzania.

Why do rift valleys have volcanoes?

Rift volcanoes form when magma rises into the gap between diverging plates. They thus occur at or near actual plate boundaries. … Earthquake swarms and volcanic eruptions occur when the stretching exceeds the strength of the near-surface rocks, which then fracture along steeply dipping cracks parallel to the rift.
