Rift valley lakes
Baikal is both the deepest lake in the world and, with 20% of all of the liquid freshwater on earth, has the greatest volume.
Lake Tanganyika, second by both measures, is in the Albertine Rift, the westernmost arm of the active East African Rift.

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. Oceanic rift zones occur deep in ocean basins where two oceanic plates are separating.
Which countries does the Great Rift Valley run through?
Great Rift Valley, geological fault system of SW Asia and E Africa. It extends c.3,000 mi (4,830 km) from N Syria to central Mozambique. The northernmost extension runs S through Syria and Lebanon, the Jordan valley, the Dead Sea, and the Gulf of Aqaba.
What is the longest rift on Earth’s surface?
Lake Baikal also has the largest volume of liquid freshwater in the world—a staggering 23,615 cubic kilometers (5,700 cubic miles). The Dead Sea is a rift lake in the Jordan Rift Valley. Although the Dead Sea is not the world’s deepest lake, the deep Jordan Rift makes it the lowest land elevation on Earth.
What caused the Great Rift Valley?
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.
On which continent is most of the Great Rift Valley located?
The Rift Valley, also known as the Great Rift Valley or Eastern Rift Valley, is a geological feature due to the movement of tectonic plates and mantle plumes that runs south from Jordan in southwest Asia, through East Africa and down to Mozambique in southern Africa.
What was found in the Great Rift Valley?
The Great Rift Valley is part of an intra-continental ridge system that runs through Kenya from north to south. It is part of the Gregory Rift, the eastern branch of the East African Rift, which starts in Tanzania to the south and continues northward into Ethiopia.
What happens when tectonic plates pull apart?
Two main tectonic structures are spreading centers and subduction zones. Spreading centers occur at the boundary between two plates that are moving apart, called divergent plate boundaries. Here the plate motion opens a gap between the plates and magma from the mantle rises up through it.
What will a rift valley eventually become?
A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault. A rift valley is formed on a divergent plate boundary, a crustal extension or spreading apart of the surface, which is subsequently further deepened by the forces of erosion.
How deep is the rift valley?
It contains the Rift Valley lakes, which include some of the deepest lakes in the world (up to 1,470 metres (4,820 ft) deep at Lake Tanganyika).
Is Mt Kilimanjaro in the Great Rift Valley?
Kilimanjaro is the largest of an E-W belt of about 20 volcanoes near the southern end of the East African Rift Valley. Kilimanjaro is a triple volcano with the youngest and central peak of Kibo being 7.5-8.7 miles (12-14 km) from Shira to the west and Mawenza to the east.
Where is the Great African Rift Valley?
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.
What is the difference between Rift and Ridge?
1 Answer. Divergent boundaries occur at the boundary between plates. A divergent boundary is where two tectonic plates are actively being pushed apart. Divergent boundaries create rift valleys on land and eventually ridges on ocean floors, where hotter material wells up from the mantle, cools and form new crust.
What caused the African Rift Valley?
The East African Rift is one of the great tectonic features of Africa, caused by fracturing of the Earth’s crust. This astronaut photograph of the Eastern Branch of the Rift (near Kenya’s southern border) highlights the classical geologic structures associated with a tectonic rift valley.
What planet has the longest valley?
How old is the Great African Rift Valley?
The eastern branch of the rift passes through Ethiopia and Kenya, and the western branch forms a giant arc from Uganda to Malawi. The eastern branch formed around 25 to 30 million years ago, whereas the western branch formed only 10 to 15 million years ago — or at least that’s what scientists thought.
What is causing the East African Rift?
The tear, which continues to grow, caused part of the Nairobi-Narok highway to collapse. Initially, the appearance of the crack was linked to tectonic activity along the East African Rift. The Earth’s lithosphere (formed by the crust and the upper part of the mantle) is broken up into a number of tectonic plates.
What two plates formed the Great Rift Valley?
The rift, a narrow zone, 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) annually.
How were the deep lakes in the Great Rift Valley created?
It is not in the rift valley, instead occupying a depression between the eastern and western rifts formed by the uplift of the rifts to either side. Lakes Victoria, Tanganyika, and Malawi are sometimes collectively known as the African Great Lakes. Approximately 1,500 cichlid fish (Cichlidae) species live in the lakes.
Which is the largest lake in Africa?
These are the largest lakes in Africa.
- Lake Kivu.
- Lake Mweru.
- Lake Rukwa.
- Lake Albert.
- Lake Turkana.
- Lake Nyassa.
- Lake Tanganyika.
- Lake Victoria. Lake Victoria is the largest freshwater body in Africa and the second largest in the world, smaller only than Lake Superior, which is one of North America’s Great Lakes.
What animals live in the Great Rift Valley?
Mammals abound in the Great Rift Valley. Lions, leopards, African elephants, rhinos, buffaloes, cheetahs, giraffes, antelopes, zebras and primates ranging from mountain gorillas to chimpanzees all call the Africa’s Rift Valley home. Mountain gorillas are some of the most iconic animals endemic to the Rift Valley.
