The Great Rift Valley was formed when two tectonic plates split apart and left a rift . ... You would find mountains, escarpments, volcanoes, rivers, and large lakes in the Great Rift Valley.
Which feature of Earth is created at mid ocean ridges quizlet?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
Which statements best describe how the Great Rift Valley in Africa formed check all that apply?
Explanation: The statement that best describes how the Great Rift Valley in Africa formed is that they formed when the crust pulled apart . This is geologically known as divergence. The Arabian plate and the Nubian/Somali plate are divergent plates.
What action is creating the rift valley in Africa?
Associated with the Jordan Rift Valley to the south is the Red Sea Rift. 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.
What type of boundary is found at the Great Rift Valley in Africa?
The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa.
How is the 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.
Where does the Great Rift Valley begin and end quizlet?
Where does the Great Rift Valley begin and end? This natural wonder stretches from Syria in Southwest Asia to Mozambique in the Southeastern part of Africa .
Which feature of Earth is created at mid ocean ridges?
Explanation: Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt .
What is the Earth’s outermost layer?
The upper part of the mantle becomes solid. The outermost layer, called the crust , is solid, too. Together, these solid parts are called the lithosphere. Earth’s crust is made up of hard rocks.
Which events are associated with convergent boundaries quizlet?
– Heat from Earth’s interior causes lithospheric plates to collide at convergent plate boundaries, causing volcanoes. – Heat from Earth’s interior causes currents of hot rising magma and cooler sinking magma to flow, moving the crust along with them.
What is the Great Rift Valley and why is it important?
The system of rift valleys that characterizes the African continent represents a perfect environment to understand the evolution of mankind ; for the important paleoanthropological discoveries in Ethiopia, Kenya, Tanzania, Uganda and Zaire, the African rift valleys are indeed considered the “cradle of mankind”, that is ...
What is an example of a rift valley?
Very few active rift valleys are found on continental lithosphere. The East African Rift, the Baikal Rift Valley, the West Antarctic Rift , and the Rio Grande Rift are Earth’s major active continental rift valleys. The East African Rift is part of the “Great Rift Valley” system discussed below.
What are the characteristics of rift valley?
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.
In which two countries is 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.
Which countries does the Rift Valley pass through?
| Name of basin Total area of basin Area in the country | Uganda 4 514 | Kenya 102 452 | Southern lakes: 178 800 | Kenya 25 000 |

Is the Great Rift Valley a divergent boundary?
Great Rift Valley (The Best Example of a Divergent Boundary ) ... In a southwest direction, the fault continues as the Great Rift Valley, which split the older Ethiopian highlands into two halves. In eastern Africa, the valley divides into the Eastern Rift and the Western Rift.
