Why did the Great Rift Valley grow?
Why does rifting happen? When the lithosphere is subject to a horizontal extensional force it will stretch, becoming thinner. Eventually, it will rupture, leading to the formation of a rift valley. This process is accompanied by surface manifestations along the rift valley in the form of volcanism and seismic activity.
How is the rift valley growing?
A rift valley refers to a lowland region where tectonic plates rift, or move apart. The rifts are growing larger as two tectonic plates, the Somali plate in the east and the Nubian plate in the west, move away from each other.
How do animals get Rift Valley Fever?
Rift Valley fever (RVF) is a viral disease most commonly seen in domesticated animals in sub-Saharan Africa, such as cattle, buffalo, sheep, goats, and camels. People can get RVF through contact with blood, body fluids, or tissues of infected animals, or through bites from infected mosquitoes.
What is the effect of rift valley?
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.
Is there a cure for Rift Valley fever?
There are no FDA-approved treatments for Rift Valley Fever. Because most cases of RVF are mild and self-limiting, a specific treatment for RVF has not been established. Symptoms of mild illness such as fever and body aches can be managed with standard over-the-counter medications.
What type of disease is Rift Valley fever?
Rift Valley fever (RVF) is an acute viral hemorrhagic fever that is most commonly seen in domesticated animals (such as cattle, buffalo, sheep, goats, and camels) and can also cause illness in people. The disease is caused by RVF virus (RVFV), a member of the genus Phlebovirus in the order Bunyavirales.
Is Africa cracking in half?
Scientists say a new ocean will form in Africa as the continent continues to split into two. It is an active continental rift that began millions of years ago, splitting at 7mm annually.
How fast is Africa splitting apart?
The three plates are separating at different speeds. The Arabian plate is moving away from Africa at a rate of about 1 inch per year, while the two African plates are separating even slower, between half an inch to 0.2 inches per year, according to Macdonald.
How is Rift Valley fever spread to cattle?
Rift Valley Fever is a viral disease of cattle and sheep that was first discovered in the Rift Valley of Kenya. The disease is spread to livestock through the bite of infected mosquitoes during years of heavy rainfall. The disease causes high death rates in young animals and abortions in older animals.
What are the effects of the Great Rift Valley?
Sections of the Great Rift Valley reveal the dynamic tectonic forces that are shearing, tearing, erupting, and collapsing Earth’s surface. These forces create a void that will eventually be occupied by the ocean. Until then, they create new landscapes, places of habitation, routes of migration, places of freshwaters, and ever-new strata of history.
How many birds cross the Great Rift Valley each year?
The Great Rift Valley is the second largest bird migration corridor in the world. Each year, approximately 1.5 million birds cross the valley and traverse the Mediterranean Sea, the Nile Valley, the Red Sea, and the East African Rift Valley.
