What is the Great Rift Valley used for?
This area is part of the Great Rift Valley, where Africa is slowly pushed and pulled apart by uprising material in earth’s mantle. Eventually, the rift will become deep enough to host a new ocean, separating Eastern Africa from the rest of the continent.
What is the example of Rift Valley?
The most extensive of the continental rift valleys are those of the East African Rift System, which extend northward to the Red Sea and eastward into the Indian Ocean. Other notable examples include the Baikal Rift Valley (Russia) and the Rhine Rift Valley (Germany).
Why is the Rift Valley important to Africa?
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 …
How do rift valleys form for kids?
tectonic activity creates rift valleys The valleys form when continental crust is pulling apart allowing the land to drop down between parallel faults. These valleys also form when oceanic plates are moving apart forming a divergent boundary.
Do rift valleys create new crust?
As tectonic plates move away from one another at mid-ocean ridges, molten rock from the mantle may well up and harden as it contacts the frigid sea, forming new oceanic crust at the bottom of the rift valley.
How a rift valley is formed?
A rift valley is a lowland region formed by the interaction of Earth’s tectonic plates. 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.
Which is the longest rift valley in the world?
One of the world’s largest rift valleys is the EAR, approximately 3,700 miles long and 30-40 miles wide. The rift valley is so big that it is slowly splitting Africa in two. The larger Nubian tectonic plate encompasses most of the continent, whereas the smaller Somali plate carries the Horn of Africa.
Why do rift valleys have volcanoes?
Rift volcanoes form when magma rises into the gap between diverging plates. They thus occur at or near actual plate boundaries. Earthquake swarms and volcanic eruptions occur when the stretching exceeds the strength of the near-surface rocks, which then fracture along steeply dipping cracks parallel to the rift.
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.
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.
How does Rift Valley fever affect the body?
Rift Valley fever (RVF) is a viral zoonosis that primarily affects animals but also has the capacity to infect humans. Infection can cause severe disease in both animals and humans. The disease also results in significant economic losses due to death and abortion among RVF-infected livestock.
What are common in rift valleys and oceanic ridges?
Rift valleys and ocean ridges are common in the aspect that they are both similar seismic structures, meaning both were formed out of the moving tectonic plates. Furthermore, rift valleys and ocean ridges were the result of two plates, moving away from each other, respectively the continental and oceanic plates.
What are the common in the four pictures of rift valleys and oceanic ridges?
Answer: The common among the pictures is the formation of divergent plate boundary, where it forms the rift valleys and oceanic ridges. The four presented pictures are most likely bodies of water that has a tight space of water movement.
What is the difference between Rift Valley and oceanic ridges?
The major difference between different types is what type of plate the divergent boundary is between. If the boundary is found between two continental plates you are left with a rift valley. If two oceanic plates begin moving away from each other it creates a mid-oceanic ridge.
What is the difference between Ridge and rift?
The two words are nearly opposites. A rift is a break, crack, split, or fissure. If you imagine a glacier breaking into two pieces with a long narrow crevice between the two halves, you are imagining a rift. A ridge is high narrow elevation, such as an extended narrow hilltop or a mountain range.
What is the difference between a trench and a rift valley?
A rift valley is elongate depression that develops at a divergent plate boundary (ie. A trench is a long, narrow, steep-sided depression of the seafloor formed where a sub ducting oceanic plate sinks into the mantle causing the seafloor to bend downward like a flexed diving board(Earth, pg316).
What’s a rift?
In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Major rifts occur along the central axis of most mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates.
