Are the African and Arabian Plate convergent or divergent?
divergent boundary
A divergent boundary with the African Plate called the Red Sea Rift while in Arabian Plate is a left-lateral transform fault boundary called the Dead Sea Rift. A minor tectonic plate consisting mostly of the Arabian Peninsula, extending northward to Mesopotamia and the Levant.
Is the Arabian Plate a convergent boundary?
The Zagros and Makran Mountains in Iran and the Taurus Mountains in southern Turkey are, respectively, the eastern and northern boundaries of the Arabian Plate, which are classified as convergent plate boundaries that represent the zone of collision between the Arabian Plate and the Eurasian Plate.
What type of plate boundary is formed between Arabian and African plates?
The type of tectonic plate boundary that occurs between the African Plate and the Arabian Plate is a divergent plate boundary.
What type of tectonic plate is the Arabian Plate?
continental plates
The Arabian Plate is a minor tectonic plate in the northern and eastern hemispheres. It is one of three continental plates (along with the African and Indian plates) that have been moving northward in geological history and colliding with the Eurasian Plate.
Is the East African Rift a divergent boundary?
The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa. Here the eastern portion of Africa, the Somalian plate, is pulling away from the rest of the continent, that comprises the Nubian plate.
How was the Arabian Plate formed?
The Arabian Plate originated ∼ 25 Ma ago by rifting of NE Africa to form the Gulf of Aden and Red Sea. It is one of the smaller and younger of the Earth’s lithospheric plates.
Which plate forms a boundary with the African Plate?
Boundaries. The western edge of the African Plate is a divergent boundary with the North American Plate to the north and the South American Plate to the south which forms the central and southern part of the Mid-Atlantic Ridge.
Which plate forms a boundary with African Plate?
What boundary that East African Rift is an example?
The East African Rift Valley is an example of a divergent boundary in an area of continental crust. It is one the geologic wonders of the world, a place where the earth’s tectonic forces are presently trying to create new plates by splitting apart old ones.
What is convergent boundary?
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
What type of plate boundary is between South America and Africa?
Students figure out: The South American and African plates moved apart as a divergent boundary formed between them and an ocean basin formed and spread.
What type of divergent boundary is the East African Rift?
Tectonic activity splits continental crust much in the same way it does along mid-ocean ridges. The East African Rift Valley is an example of a divergent boundary in an area of continental crust.
What two plates are involved in the East African Rift?
Throughout the East African Rift, the continent of Africa is splitting in two. The African plate, sometimes called the Nubian plate, carries most of the continent, while the smaller Somali plate carries Horn of Africa. The two major rift valley systems of the East African Rift are the Gregory Rift and the Western Rift.
What plates have convergent boundaries?
Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere.
Which plate boundaries are convergent?
When two tectonic plates move toward each other and collide, they form a convergent plate boundary. There are three types of convergent plate boundaries: oceanic-oceanic boundaries, oceanic-continental boundaries, and continental-continental boundaries. Each one is unique because of the density of the plates involved.
Is African Plate oceanic or continental?
The African Plate is both oceanic and continental. It has the whole African continent on top of it as well as the oceanic crust of the Atlantic Ocean.
How does the East African Rift relate to plate tectonics?
A narrow zone, the rift is a developing divergent tectonic plate boundary where the African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate, at a rate of 6–7 millimetres (1⁄4–9⁄32 inch) per year.
What are 3 examples of convergent boundaries?
Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean.
- Continent‐continent convergence results when two continents collide.
- Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust.
What are the examples of convergent boundary?
Examples. The collision between the Eurasian Plate and the Indian Plate that is forming the Himalayas. Subduction of the northern part of the Pacific Plate and the NW North American Plate that is forming the Aleutian Islands. Subduction of the Nazca Plate beneath the South American Plate to form the Andes.
What are 2 examples of convergent boundaries?
When two tectonic plates move toward each other and collide, they form a convergent plate boundary. There are three types of convergent plate boundaries: oceanic-oceanic boundaries, oceanic-continental boundaries, and continental-continental boundaries.
