You asked: Why is the west coast of Africa a plate boundary?

The west coast of africa is considered a divergent boundary. In the north you have the North American Plate and in The south you have the South American Plate. These two plates move away from each other and therefore known/called the mid-ocean ridges.

Is the west coast of Africa a plate boundary?

The west coast of Africa is a plate boundary.

What kind of plate boundary is in Africa?

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.

What kind of plate boundary occurs on the West Coast of the United States?

The transform plate boundary between the Pacific and North American Plates in western California formed fairly recently. About 200 million years ago, a large tectonic plate (called the Farallon Plate) started to subduct beneath the western edge of North America.

Is the west coast of South America a plate boundary?

The west coast of South America is a subduction zone, which means that the oceanic plate, called the Nazca plate, is being forced beneath the adjacent continental plate. … The complexity of plate tectonics in this region makes it a locality of interest for geologists.

What kind of plate boundary is found between the African and Arabian plates?

The Arabian Plate is rifting away from the African plate along an active divergent ridge system, to form the Red Sea and Gulf of Aden.

Is Sicily on African plate?

Sicily. While people generally consider the island of Sicily, just off the coast of the Italian Peninsula, to be European, it is in fact a part of the African plate.

Is San Andreas Fault a plate boundary?

Tectonic Plate Boundaries

The San Andreas fault is a transform plate boundary, accomodating horizontal relative motions.

Is the Nazca plate convergent or divergent?

The Nazca plate is an oceanic tectonic plate in the southeastern Pacific Ocean that shares both convergent and divergent boundaries, corners multiple triple junctions, contains three seamount chains, overrides four hotspots, and is responsible for the creation of the Andean orogeny (Figure 1).

What type of plate boundary is the Andes Mountains?

The Andes Mountain Range was formed from the result of the Nazca Plate being subducted under the western edge of the South American Plate. A subduction zone occurs when a heavier and denser tectonic plate (most commonly an Oceanic plate) goes under a lighter, less denser plate (most commonly a Continental plate).

What landforms are created by convergent boundaries?

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.

At what type of boundary would you observe subduction?

Subduction occurs when two plates collide at a convergent boundary, and one plate is driven beneath the other, back into the Earth’s interior.

What two plates make up the San Andreas Fault?

Two of these moving plates meet in western California; the boundary between them is the San Andreas fault. The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east), causing earthquakes along the fault.

Why is the Nazca plate a divergent boundary?

Divergent Boundary – The Nazca Plate. Divergent boundaries are defined as boundaries where two plates are moving away from one another. … The reason that this ridge has formed is as these two plates move away from one another it creates areas of lower pressure in the lithosphere.

What type of plate boundary is found between the South American and Nazca plates?

Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Range) and subduction of the Juan de Fuca Plate under North America (creating the mountains Garibaldi, Baker, St.

What is the plate boundary between Nazca and South America?

The ongoing subduction, along the Peru–Chile Trench, of the Nazca Plate under the South American Plate is largely responsible for the Andean orogeny. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise and the Chile Rise respectively.
