Where is the Great Rift Valley?

Where is the Great Rift Valley?

The most well-known rift valley on Earth is probably the so-called “Great Rift Valley System” which stretches from the Middle East in the north to Mozambique in the south. The area is geologically active, and features volcanoes, hot springs, geysers, and frequent earthquakes.

Where is the East African Great Rift Valley located?

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. The system is some 4,000 miles (6,400 km) long and averages 30–40 miles (48–64 km) wide.

How the Great Rift Valley was formed in East Africa?

The East African Rift Valley, as the region is known, formed where the Somalian and Nubian plates are pulling away from the Arabian Plate. The eastern branch of the rift passes through Ethiopia and Kenya, and the western branch forms a giant arc from Uganda to Malawi.

Why the Great Rift Valley in Africa is a good example of divergent convergence?

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.

Which is the longest rift valley of the world?


World Rift/Valley Length
Earth Great Rift Valley 6,000 km (3,700 mi)
Canadian Arctic Rift System 4,800 km (3,000 mi)
West Antarctic Rift System
Midcontinent Rift System 2,000 km (1,200 mi)

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.

Why is the Great Rift Valley 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.

Why is the Great Rift Valley an important physical feature?

The erosion patterns of the highlands have caused a buildup of sediments on the rift valley floor, creating a favorable environment for the preservation of biological remains, including both human and animal remains. Important fossils and bones of several hominid species have been found in the Great Rift Valley.

How does Rift Valley fever affect the body?

Most commonly, people with RVF have either no symptoms or a mild illness associated with fever and liver abnormalities. Patients who become ill usually experience fever, generalized weakness, back pain, and dizziness at the onset of the illness.

What part of the body does valley fever affect?

It happens when the infection spreads from the lungs to other parts of the body through the bloodstream. It can affect many organs, and particularly the skin, liver, brain, bones, meninges, and heart. Signs and symptoms vary depending on which parts of the body are affected.

How do you treat 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 are the symptoms of Rift Valley Fever?

Rift Valley fever (RVF) is a viral disease of humans and livestock that can cause mild to severe symptoms….

Rift Valley fever
Symptoms Fever, muscle pains, headaches
Complications Loss of sight, confusion, bleeding, liver problems
Duration Up to a week
Causes Phlebovirus spread by an infected animal or mosquito

What four types of animals are affected by 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.

Which of the following symptoms is are most common in humans with Rift Valley Fever?

Most commonly, people with RVF have either no symptoms or a mild illness that includes fever, weakness, back pain, and dizziness at the onset of illness.

Is Rift Valley fever an epidemic?

Following small sporadic outbreaks of Rift Valley fever in 2008-2009, a widespread epidemic occurred in 2010 and 2011 in South Africa. More than 250 human cases occurred, including 25 deaths, and more 14,000 animal cases, with 8,000 deaths, occurring in animals.

Why is it called Rift Valley Fever?

Name and nature of infecting organism Rift Valley fever (RVF) is a disease of domestic ruminants, caused by an arbovirus belonging to the Phlebovirus genus (Bunyaviridae family). The RVF virus was first identified in 1931 during an investigation into an epidemic among sheep on a farm in the Rift Valley in Kenya.

What is the vector for Rift Valley Fever?

Mosquitoes are both a reservoir and vector for RVFV, which means that they can maintain virus for life and transmit it to their offspring via eggs. After periods of heavy rainfall and flooding, an increased number of RVF virus-infected mosquitos may hatch and pass virus to people and animals.

Is there a vaccine for Rift Valley Fever?

CDC researchers have developed a vaccine. During early testing, all vaccinated animals were protected against the RVF virus. There were no negative side effects. The vaccine is also inexpensive to produce, and this makes it an affordable option for developing countries.

What is the Rift Valley virus?

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.

How does Rift Valley fever spread?

People usually get Rift Valley fever through contact with blood, body fluids, or tissues of infected animals, mainly livestock such as cattle, sheep, goats, buffalo, and camels.

Where are you most likely to catch Valley Fever?

Who gets Valley fever? Anyone who lives in or travels to the southwestern United States (Arizona, California, Nevada, New Mexico, Texas, or Utah), or parts of Mexico or Central or South America can get Valley fever. Valley fever can affect people of any age, but it’s most common in adults aged 60 and older.

Is Rift Valley Fever in the United States?

While it is true that mosquitoes in North America are able to transmit the virus that causes RVFV, there is a small (but not negligible) risk that an outbreak could emerge in the U.S. In the context of the World Cup, for instance, a traveler would have to be infected in South Africa, travel to the U.S., and be bitten …

How can Rift Valley Fever be prevented in animals?

Avoid contact with blood, body fluids, or tissues of infected animals. People working with animals in RVF-endemic areas should wear appropriate protective equipment (such as gloves, boots, long sleeves, and a face shield) to avoid any exposure to blood or tissues of animals that may potentially be infected.

Is Rift Valley Fever a neglected tropical disease?

Rift Valley fever (RVF) is a zoonotic disease, meaning that it can be transmitted to humans from animals, but the RVF virus can also be transmitted by mosquito bites.In recent decades, formerly neglected tropical infectious agents have been “rediscovered” following their introduction and spread into naïve populations.

Can goats get diseases from mosquitoes?

Rift Valley fever virus (RVFV) is a zoonotic mosquito-borne virus that causes acute infections in ruminants such as goats, cattle, sheep, and camels. Large outbreaks of RVFV have mainly occurred in Sub-Saharan Africa.
