This process of continental breakup is strongly associated with volcanoes because, as the land splits, molten rock rises into the Earth’s crust. Some of this magma makes it to the surface and forms volcanoes. Most of East Africa’s volcanoes are currently dormant. But they could erupt in the future.
Does East Africa have volcanoes?
The East African Rift Zone includes a number of active and dormant volcanoes, among them: Mount Kilimanjaro, Mount Kenya, Mount Longonot, Menengai Crater, Mount Karisimbi, Mount Nyiragongo, Mount Meru and Mount Elgon, as well as the Crater Highlands in Tanzania.
Why are there deep lakes and high volcanoes in East Africa?
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 is the most common type of volcano in East Africa?
Background. Nyamuragira is Africa’s and one of the world’s most active volcano. It erupts roughly every two years, producing large fluid lava flows. Nyamuragira is is a massive high-potassium basaltic shield volcano located about 25 km north of Lake Kivu in the East African Rift Valley NW of Nyiragongo volcano.
What is causing the East African Rift?
The East African Rift is one of the great tectonic features of Africa, caused by fracturing of the Earth’s crust. … The Somalian plate—which is moving away in the other direction—lies to the other side and includes the Horn of Africa.
Is Africa breaking apart?
It is an active continental rift that began millions of years ago, splitting at 7mm annually. The regular eruption of volcanoes along the rift and new insights into the break up of continents adds to the belief that the continent may be splitting to form a new ocean.
What are the two major inactive volcanoes in East Africa?
Two neighboring volcanoes in Zaire’s (today’s Democratic Republic of the Congo) Virunga National Park, Nyamuragira and Nyiragongo, are responsible for nearly two-fifths of Africa’s historical eruptions.
Which is the deepest lake in East Africa?
the largest of Africa’s Great Rift Valley lakes, the second largest of all African lakes, and the fifth largest of the world’s lakes; the deepest of all African lakes and the second deepest lake in the world; and.

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.
What is the most important river in East Africa?
Lakes and Rivers Burundi’s rivers flow into two basins of two major rivers, the Zaire and the Nile. The most important river flowing into the Zaire basin is the Rusizi, which has its source in Lake Kivu and forms the border between Zaire and Burundi.
What is the largest volcano in Africa?
Mount Kilimanjaro is a dormant volcano in Tanzania. It is the highest mountain in Africa with an elevation of 19,341 feet.
Is there a volcano in Ghana?
The Buem volcanic rocks of Ghana form part of the Dahomeyide Chain on the southeastern flank of the West African Craton. … Gravity data suggest that the outcrop is a section across a rift zone of a large volcano whose eroded core now lies under the Voltaian Basin.
Which volcano erupts the coldest lava on Earth?
Because of its very unusual composition, carbonatite is literally the coolest lava on earth, erupting at 500-600 degrees Centigrade (930-1,100 degrees F), compared with 1,160 degrees C (2,120 degrees F) for lava from Kilauea’s current eruption.
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.
Is Africa moving towards Europe?
For millions of years the African plate, which contains part of the Mediterranean seabed, has been moving northward toward the Eurasian Plate at a rate of about an inch every 2.5 years (a centimeter a year).
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.
