In the western Mediterranean, the relative motions of the Eurasian and African plates produce a combination of lateral and compressive forces, concentrated in a zone known as the Azores–Gibraltar Fault Zone.
What are the major tectonic events in Africa?
The most recent tectonic events affecting Africa are the East African rift (Fig. 1) that initiated 30–40 Ma (Burke 1996) and now extends from Afar to Mozambique and the Maghrebides Belt of NW Africa that is related to the Alpine orogeny.
How many tectonic plates does Africa have?
This rift is a result of the eastern area of Africa diverging from the western area. Geologists debate whether this means that Africa is in fact composed of two plates, or if the African plate itself is splitting into two pieces.
What are the three major types of fault boundaries?
Tectonic Plates and Plate Boundaries
- There are three main types of plate boundaries:
- Convergent boundaries: where two plates are colliding.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
What countries are affected by the African plate?
North Africa forms the northern margin of the African Plate and comprises the countries Morocco, Algeria, Tunisia, Libya, and Egypt (Figure 1).
Is Africa on a tectonic plate?
The African Plate is a major tectonic plate straddling the Equator as well as the prime meridian. It includes much of the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges.
Who named Africa?
Some believe that the word “Africa” came from the Romans, who named the land they discovered on the opposite side of the Mediterranean after a Berber tribe living in the Carthage area (now modern-day Tunisia). Different sources give different versions of the tribe’s name, but the most popular is Afri.
What is the largest tectonic plate?
California is located at the seam of the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles, and the Northern American plate.
What is the smallest tectonic plate?
One of the smallest of Earth’s tectonic plates, the Juan de Fuca Plate is a remnant part of the once-vast Farallon Plate, which is now largely subducted underneath the North American Plate.

What are the 5 plate boundaries?
What are the major plate tectonic boundaries?
- Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
- Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
- Transform: shearing; plates slide past each other. Strike-slip motion.
What are some examples of divergent boundaries?
- Mid-Atlantic Ridge.
- Red Sea Rift.
- Baikal Rift Zone.
- East African Rift.
- East Pacific Rise.
- Gakkel Ridge.
- Galapagos Rise.
- Explorer Ridge.
Do Transform boundaries cause volcanoes?
Volcanoes do not typically occur at transform boundaries. One of the reasons for this is that there is little or no magma available at the plate boundary.
Is Africa breaking apart?
The African continent is slowly separating into several large and small tectonic blocks along the diverging East African Rift System, continuing to Madagascar — the long island just off the coast of Southeast Africa — that itself will also break apart into smaller islands.
Is Africa continent breaking apart?
Scientists say a new ocean is being born. New satellite measurements are offering valuable tools to study the tectonic rift in one of the most geologically unique spots on the planet.
Why is Africa divided?
This conference was called by German Chancellor Bismarck to settle how European countries would claim colonial land in Africa and to avoid a war among European nations over African territory. … All the major European States were invited to the conference.
