The Afar region in Northern Ethiopia is the centre of a “Y” shaped rift system, where the continental lithosphere is being stretched and is splitting. 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.
What type of plate boundary is the Arabian plate?
It has three main well-defined and sharp plate boundaries, and it is surrounded by three major plates, African, Eurasian and Indian plates. The Red Sea and Gulf of Aden form the divergent boundary and spreading center.
What was formed when the African plate and the Arabian plate diverge?
The Arabian plate also separated from Africa at ~25 Ma, which lead to the closure of the Neotethys sea (Johnson and Stern, 2010). Subsequent rifting between Arabia and Africa resulted in the formation of the Red Sea.
What unique event is occurring between the Arabian plate and the African plate?
The Arabian plate separated from Africa approximately 25 million years ago, resulting in the closure of the subducting Tethys sea in the northeast (Johnson and Stern, 2010).
What type of boundary is African plate Indian plate?
Examples of continent-continent convergent boundaries are the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran.
What type of boundary is between the Arabian plate and Eurasian plate?
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 boundary is the Eurasian plate?
The boundary between the North America Plate and the Eurasian Plate is an example of a divergent boundary at a mid-ocean ridge.
Is Israel on the Arabian 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.
Is Arabian plate oceanic or continental?
The Arabian plate is a continental plate and has an area of 5,000,000 km 2 .
Is the Arabian Plate growing?
Covering an area of about 5,000,000 sq. km, it is located at 30°E to 75°E latitude and 10°N to 45°N longitude. The plate moves at about 4.65 cm per year in the northeast direction.
Can divergent boundaries cause volcanoes?
Most volcanoes form at the boundaries of Earth’s tectonic plates. … Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
How many tectonic plates are there 2020?
how many tectonic plates are there? There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
How many plate portions are shown?
4. A. How many portions of plates are shown? Three plates are being shown: Divergent, Convergent and Transform.
What are the three types of plate boundaries?
- Divergent boundaries — where new crust is generated as the plates pull away from each other.
- Convergent boundaries — where crust is destroyed as one plate dives under another.
- Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
What are the three types of convergent boundaries?
There are three types of convergent plate boundaries: oceanic-oceanic boundaries, oceanic-continental boundaries, and continental-continental boundaries.
