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.
Does South Africa have tectonic plates?
As you can see in the image below, Cape Town is located quite in the centre of the African Plate. The African Plate shares boundaries with 7 other plates: The Eurasian plate, North American Plate, South American Plate, Arabian Plate, Indian Plate, Australian Plate and the Antarctic Plate in the South.
Is Southern Africa two different tectonic plates?
The East African Rift Valley stretches over 3,000km from the Gulf of Aden in the north towards Zimbabwe in the south, splitting the African plate into two unequal parts: the Somali and Nubian plates.
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 two tectonic plates called in Africa?
The African plate has two of these types of plate boundaries around its border. The northern part of the plate is a convergent boundary where the African plate is subducting below the Eurasian plate. Subduction zones are convergent boundaries, and where they collide, one plate dives below the other.
What is the biggest tectonic plate in the world?
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.
Where do tectonic plates move?
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
Is Africa breaking apart?
It is an active continental rift that began millions of years ago, splitting at 7mm annually. The regular eruption of volcanoes along the rift and new insights into the break up of continents adds to the belief that the continent may be splitting to form a new ocean.
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.
Is Israel on the African tectonic plate?
Israel is situated along the border between the African Tectonic Plate and the Arabian Tectonic Plate. The border between these two plates forms part of the Great Rift Valley, the world’s most extensive geological fault, which extends southward through eastern Africa as far south as Mozambique.
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.

How many tectonic plates are there in total?
There are seven primary tectonic plates in the world, but there are also seven secondary plates and sixty tertiary plates, for a grand total of more than seventy tectonic plates. Each tectonic plate is approximate 60 miles thick and composed primarily of either continental crust or oceanic crust.
What causes the tectonic plates to move?
The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
What countries are in the African plate?
Introduction. North Africa forms the northern margin of the African Plate and comprises the countries Morocco, Algeria, Tunisia, Libya, and Egypt (Figure 1).
Are continents the same as plates?
The continents are embedded in the plates. Many continents occur in the middles of plates, not at their boundaries or edges. … Plates are composed of the Earth’s crust and upper mantle, which are collectively called the lithosphere. This layer is like an eggshell compared to the total thickness of the Earth.
What are the 12 major plates?
