What physical processes are responsible for the creation of the rift valleys of eastern Africa?
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.Click to see full answer.

Likewise, people ask, what does the creation of rift valleys indicate about the eastern part of Africa?The Rift Valley in East Africa has been a rich source of hominid fossils that allow the study of human evolution. The rapidly eroding highlands quickly filled the valley with sediments, creating a favorable environment for the preservation of remains.Likewise, what is happening at the East African Rift Valley? The East African Rift system is an example of where this is currently happening. The East African Rift Valley stretches over 3,000km from the Gulf of Aden in the north towards Zimbabwe in the south, splitting the African plate into two unequal parts: the Somali and Nubian plates. Thereof, what caused the formation of 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.How are rift valleys formed and what makes the Jordan Rift Valley significant?Rift valley formation: Plates diverge, plumes of magma heat overlying rock, heated lithosphere stretches causing it to fracture into sets of parallel faults, land between the faults collapses into deep, wide valleys separated by upright blocks of land called horsts.
