Question: 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.
When was the African rift valley formed?
It included what today is called the Lebanese section of the Dead Sea Transform, the Jordan Rift Valley, Red Sea Rift and the East African Rift. These rifts and faults were formed 35 million years ago.
Where does the East African Rift Valley start?
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.
How is a rift valley formed give one example of a rift valley?
A rift valley is formed by the submergence of a big landmass between two high block mountains, e.g. the Rhine river flows through a rift valley in its middle course.
How are rift valleys formed and what makes the Jordan Rift Valley significant?
The Jordan Rift Valley was formed many millions of years ago in the Miocene epoch (23.8 – 5.3 Myr ago) when the Arabian Plate moved northward and then eastward away from Africa. One million years later, the land between the Mediterranean and the Jordan Rift Valley rose so that the sea water stopped flooding the area.
What type of plate boundary formed 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 volcanoes have formed in the East African Rift Zone?
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.
Where does rift valley start and end?
Come and visit the Great Rift Valley. The Rift Valley starts all the way from Jordan, Middle-East, and runs through Ethiopia, Kenya, Tanzania, Congo, Malawi, and ends near the coastal town of Solada in Mozambique.
How are rift valleys formed Class 9?
They are formed due to the collision of tectonic plates. They are formed due to the sinking of land between two normal faults or deep slopes. They are formed due to the sinking of land between two river basins.
How are mountains created Class 9?
Earthquakes and volcanic activities are described as sudden forces. These forces are described as ‘Constructive Forces’ because they create relief features on the surface of the earth. As volcanic erruptions result in the formation of volcanic mountains, extensive plateaus and also plains.
What is meant by landform give two example?
Landforms are natural features of the landscape, natural physical features of the earth’s surface, for example, valleys, plateaus, mountains, plains, hills, loess, or glaciers. examples- Mountains, hills, plateaus, and plains are the four major types of landforms.
How was Great Rift Valley formed?
Geologists know that the Rift Valley was formed by violent subterranean forces that tore apart the earth’s crust. These forces caused huge chunks of the crust to sink between parallel fault lines and force up molten rock in volcanic eruptions.
How are Rift Valley lakes formed?
Lakes of the Rift Valley – Information on the Rift Valley Lakes. – formed about 25 million years ago by the violent separation of two of the earth’s continental plates floating on the molten magma of its core.
How are rift valleys and block mountains formed?
Block mountains and rift valleys are associated landform as they are formed by the divergent plate boundaries due to the tensional forces which act on its boundary.
