What are the two branches of the Great Rift Valley?
What are the two branches of the Great Rift Valley?
In Kenya, Uganda and the fringes of South Sudan, the Great Rift runs along two separate branches that are joined to each other only at their southern end, in Southern Tanzania along its border with Zambia. The two branches are called the Western Rift Valley and the Eastern Rift Valley.
What are two physical features of the Great Rift Valley?
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.
What formed the Great Rift Valley quizlet?
The Great Rift Valley was formed when two tectonic plates split apart and left a rift. List some of the spectacular features that you would find in the Great Rift Valley. You would find mountains, escarpments, volcanoes, rivers, and large lakes in the Great Rift Valley.
How the Rift Valley was formed?
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.
Why Rift Valley is found between two block mountains?
A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may subsequently be further deepened by the forces of erosion.
Is located between two block mountains?
A rift valley is found between two block mountains.
What is the Great Rift Valley and why is it important?
The Rift Valley has been a rich source of fossils that allow study of human evolution, especially in an area known as Piedmont. Because the rapidly eroding highlands have filled the valley with sediments, a favourable environment for the preservation of remains has been created.
Are trenches convergent or divergent?
No, ocean trenches do not occur at divergent plate boundaries. They are formed at convergent boundaries.
Does the Great Rift Valley have volcanoes?
Researchers are to assess largely uncharted volcanoes in the East African Rift Valley, home to vast mammal migrations, mountain gorillas, spectacular peaks and fertile plains. The region’s volcanoes, numbering more than 100, are shrouded in mystery. Prior to its eruption, the volcano was believed to be dormant.
Why are there so many volcanoes in the Great Rift Valley?
A new spreading centre may be developing under Africa along the East African Rift Zone. When the continental crust stretches beyond its limits, tension cracks begin to appear on the Earth’s surface. Magma rises and squeezes through the widening cracks, sometimes to erupt and form volcanoes.
What is the most dangerous volcano in Africa?
Mount Nyiragongo
Is there a volcano in Somalia?
This stratovolcano is part of the Afar Triangle (Afar Depression), a highly active volcanic region which includes Erta Ale. An eruption on September 26, 2005 created a large fissure in the ground, known as the Dabbahu fissure….

What country has the most volcanoes in Africa?
Another hotspot for volcanoes is on the African continent, where the African Plate meets the Arabian Plate, which is why Kenya (23), Tanzania (10) and Ethiopia (57) boast a wealth of volcanoes.
Does Africa have a volcano?
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 the most dangerous volcano on Earth?
Kilauea
Do we have volcano in South Africa?
Marion Island, South Africa’s only historically active volcano, lies at the SW end of a submarine plateau immediately south of the SW Indian Ocean Ridge, opposite Prince Edward Island. The 1230-m-high island is dotted by about 150 cinder cones, smaller scoria cones, and coastal tuff cones.
Which one is the extinct volcano of Africa?
Mount Elgon
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.
