PDF Types of Plate Boundaries Map Identification Activity (Note that the image is oriented so that north is to the lower left.) Subduction zones are convergent boundaries, and where they collide, one plate dives below the other. It includes much of the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges. Map of East Africa showing some of the historically active volcanoes (red triangles) and the Afar Triangle (shaded, center) -- a so-called triple junction (or triple point), where three plates are pulling away from one another: the Arabian Plate, and the two parts of the African Plate (the Nubian and the Somalian) splitting along the East African Rift Zone. Canary Islands are located in the northwestern part of the Nubian (African) tectonic plate, relatively far from major plate boundaries and close to the thickened Western African craton continental . The African Plate is a major tectonic plate straddling the Equator as well as the prime meridian. example of land based rifting. A divergent tectonic plate boundary separates the majority of the African and Arabian plates. For example, the African major plate contains the whole continent of Africa as well as the surrounding oceanic crust of the Atlantic Ocean. Because of this, all of the other plates have moved away from African creating divergent boundaries on three of the sides. The Somalian plate—which is moving away in the other direction—lies to the other side and includes the Horn of Africa. Movements of the Arabian Plate. According the theory of plate tectonics, Earth's outer shell is made up of a series of plates.The map above shows names and generalized locations of Earth's major tectonic plates. Adriatic Plate. This microplate is bordered by an orogenic belt, the peri-Adriatic mountain chain that runs through Italy and Greece, in the region surrounding the Adriatic Sea (Channell and . The west side shares a divergent plate boundary with the North American plate. Transform Plate Boundaries The African plate has two of these types of plate boundaries around its border. At a convergent plate boundary, one plate dives ("subducts") . Map of the North American - Caribbean tectonic plate boundary. The Mid-Atlantic Ridge corresponds to the boundary between the South American plate and the African plate, and the boundary between North American plate and Eurasian plate. A. mid-ocean ridge Organization of African Intra-Plate Tectonics * James W. Granath¹ and William Dickson² . The African plate moves north so it pressures the boundaries with the european one, this is why we have earthquakes around Spain-Portugal, earthquakes and volcanic eruptions in Italy and earthquakes in Greece, especially the ones around Crete. Above: East African Rift Valley, Ethiopia. As Fig. What type of boundary is between Australia and African plate? Bold numbers are the years of moderately large (larger than about M7) historical earthquakes written next to their approximate location. The African plate boundary consists of both convergent and. name the 3 types of plate boundaries. Burke and Dewey favoured two sub-plates, a west African and an east African, but later authors recognised that . 2. 1972) (Emerick and Duncan, 1982). When this happens, water can flow into the valley. Subduction zones are convergent boundaries, and where they collide, one plate dives below the other. the Africa-Anatolia plate boundary and to discuss its present tectonic setting, we have analyzed six NW-SE and one NE-SW trending seismic profiles, which provide the first deep seismic reflection images across the area of the eastern Cyprean Arc (Figure 2). As Europe and Africa move away from North and South America at about 1½ inches (4 centimeters) per year, the Atlantic Ocean has opened to a width of 4,000 miles . (1) From 10 Ma to 60 Ma the Somali plate began to separate from Africa via rifting - future modelling suggests that within 1 Ma, there will be a new sea between Somalia and Africa, and within 10 Ma it will be an entirely new continent (Logatchev et al. How to get repeat customers. African Plate Boundaries The northern part of the plate is a convergent boundary where the African plate is subducting below the Eurasian plate. Africa was once the center of Pangaea, the massive supercontinent that existed about 300 million years ago. This report will summery the general setting of the Africa plate with highlighting the most interested geological features in the first part. At the convergent boundary between oceanic plate and continental plate, is formed a. tension b . The African Plate is the 4th largest plate tectonic boundary on Earth. These plates move and interact with one another to produce earthquakes, volcanoes, mountain ranges, ocean trenches and other geologic processes and features.Map prepared by the United States Geological Survey. African Plate Boundaries The African plate has two of these types of plate boundaries around its border. The present-day plate boundary between Northwest Africa and Southwest Eurasia has been a matter of debate since the early plate tectonic reconstructions of McKenzie (1970) and Dewey et al. Feb. 23, 2022. A single tectonic plate can have multiple types of plate boundaries with the other plates that surround it. ACTIVITIES_Earth & Tectonics > World Plate Boundaries Activity—World Map of Plate Boundaries "Where's Waldo"-style geography. a. divergent c. transform The Nubian and Somalian plates are also separating from the Arabian plate in the north, thus creating a 'Y' shaped rifting system. Divergent plate boundaries form unique geological and chemical features like ophiolites and hydrothermal vents (aka black smokers, pictured above) which are home to extreme biological environments. Here the eastern portion of Africa, the Somalian plate, is pulling away from the rest of the continent, that comprises the Nubian plate. Mid-Atlantic ridge- spreading between N.America and Eurasia, and S.America and African plate. Copy. Includes many maps for printing, and student worksheets. (Khazaradze and Klotz, 2003). The African Plate moves at an average rate of about 2.5 centimeters per year. Arrows show the relative direction of plate motion. The point in the Afar region where the boundaries of all three plates meet is called a Triple Junction. How many tectonic plates are in Africa? Between the two plates is a rift valley. This including the type of plate boundaries and a brief history of the Africa plate. A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. It shares a convergent boundary with the Eurasian plate, subducting below the it. 10. The northern part of the plate is a convergent boundary where the African plate is subducting below the Eurasian plate. Lava flows at the surface cool rapidly to become basalt, but deeper in the crust, magma cools more slowly to form gabbro. The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa. Together with the associated Ethiopian Rift, the tectonic boundary stretches from the southern Red Sea to central Mozambique. The rift is a narrow zone that is a developing divergent tectonic plate boundary, in which the African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate (African Plate), at a rate of 6-7 mm annually. Which type of plate is found under the continents? Nazca plate's melt subducts below the South American plate, causing crustal dilation which then uses the Paleozoic sedimentary rocks to compress and form fold and thrust belt. One of these zones marks the Mediterranean-Alpine region between the Eurasian and African Plates, within which several smaller fragments of plates (microplates) have been recognized. The East African Rift Valley is an example of a divergent boundary in an area of continental crust. However, a long, vertical piece of . The Africa plate is an interested plate because it bounded with many difference major plates. The south side of the Eurasian plate neighbors the Arabian, Indian and Sunda plates. But every now and again something dramatic happens and leads to renewed questions about the African continent splitting in two. Some examples of divergent plate boundaries include the mid-Atlantic ridge, the east Pacific rise and the east African rift. How to schedule fewer meetings and get more done. Colors denote depth below sea level and elevation on land. Best Answer. East African Rift Valley, East Africa.

The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa.The EAR began developing around the onset of the Miocene, 22-25 million years ago. 5 meters) past the North American Plate along the San Andreas Fault, a transform plate boundary in California. The majority of Africa sits on top of the African Plate. Many rift valleys are part of "triple junctions," a type of divergent boundary where three tectonic plates meet at about 120° angles. convergent/ destructive, divergent/ constructive, conservative. This is the type of plate boundary that occurs between the Nazca Plate and the South American Plate. subduction- oceanic and continental . 1. Along the African Plate boundary, these two plate boundaries pull apart from each other. A tectonic plate is simply known as a plate that consist of solid rock with set of irregular shapes. These plates intersect in the Afar region of Ethiopia at what is known as a 'triple junction'. The Africa-Eurasia plate boundary displays, from west to east, a transition from simple deformation at the oceanic plate boundaries of the Atlantic, characterized by narrow seismic belts, to a broad belt of seismicity and deformation that characterizes the Alpine belt s.l. ∙ 2012-07-10 18:58:35. The map below shows the northern section of the boundary between the Arabian Plate and the African Plate. Hope you like my answer. Southeast of Florida, the Caribbean Plate is sliding east-northeast about 0.8 inches (2 centimeters) per year relative to the North American Plate. In this case, the African plate is diving below the Eurasian plate. Boundaries. Color copies are in the folder: 4. 3 types of destructive boundaries. South American plate and Nazca Plate share the longest convergent boundary on earth, featuring Andes Mountains which extends over 7000km. - the boundary between the African Plate and the Arabian Plate in the Red Sea - the Mid-Atlantic Ridge, made up of the boundary between the North American and Eurasian Plates in the North Atlantic, crossing Iceland, and the South American and the African Plates in the South Atlantic Where are the plate boundaries in South America?
