Introduction The plate tectonic plays an important role in understanding many of the geological aspects and observations and it allows scientists to prevent disasters such as earthquakes and volcanoes. The Africa plate is an interested plate because it bounded with many difference major plates. This report will summery the general setting of the Africa plate with highlighting the most interested geological features in the first part. This including the type of plate boundaries and a brief history of the Africa plate. While the second part will focus on the east African rift and its widely debate initial and current mechanism processes. General Tectonic setting of Africa The African plate is bounded by different types of plate boundaries. These plates are Divergent boundary in which the plate move away from each other in opposite direction and it create earthquake and volcanic activity. The second type is the Convergent boundary, in this type the plates move toward each other causing one plate to subduct below the other. And the third type is the Transform boundary. Plates slide past one another and usually earthquakes are associated with it (Smith and Pun 2009). The North and South American plates bounded the African plate from the west which formed the Mid-Atlantic Ridge. The plate boundaries here is mostly divergent with some transform boundaries. The African plate is spreading away from the North American plate at 28 mmyr-1 though the rate is decreasing toward the north and from the South American plate at 30 mmyr-1. While in the east the African plate is divergently bounded by the Arabian and Indian plates and they moving at average rate of 20mmyr-1. From the north, the Eurasian plate bounded the African plate; here the... ... middle of paper ... ...9-272 • Simkin,T., Unger, J., Tilling, R., Vogt, P. and Spall, H.

Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...

The great Lisbon Earthquake would occur on the seismic active region with the plate boundary of Eurasia and Africa. This boundary is believed to be a complex structure with active volcanoes and rifting that is prevalent at Azores. So many factors contributes to the complex nature of this plate boundary. It separates an oceanic crust on both sides of its western side, while on the eastern side it has a continental nature featuring the Mediterranean basin in between the plate boundaries. Specifically, this is a tectonic plate boundary within the mid-Atlantic (John
Volcanism is a major part of the Galapagos and their formation. The island chain is positioned on the Nazca Plate, which is subducting beneath the South American Plate at a geologically rapid pace of 2.5 inches per year. In addition, this Nazca Plate is located directly on top of the Galapagos Hotspot. It is here that mantle plumes melt Earth’s crust, creating volcanoes as a product. The oldest island was first shaped by this ...

First you might need to know definition of tectonics. It is a theory in geology. The lithosphere of the Earth is divided into a small number of plates which float on and travel independently over the mantle and much of the Earth’s seismic activity occurs at the boundaries of these plates. That is the official definition of Plate tectonics. secondly, this plate covers many parts of continents. plate boundaries don’t go according to Continents boundaries, they make their own boundaries. The North American plat...
This specific volcano however holds the record for longest continuous eruptions. “Mount Etna is a series of nested stratovolcanoes with four distinct summit craters. There are two central craters, called Bocca Nuova and Voragine; the Northeast crater; and the newest Southeast crater, which was formed by an eruption in 1978.” The reason why tectonic plates are so important is because they are the reason how most mountains are formed. The African tectonic plate is major for Africa because it stretches across the entire continent straddling the equator as the prime meridian. It also stretches across some oceanic crust which “lies between the continent and various surrounding ocean ridges.” The African plate actually has 6 major other plates connected to it as well, but Mount Etna is located in the North, on the Eurasian
Volcanoes are one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 are expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this, the study of volcanoes and the service that volcanologists provide to the public by way of information and predictions on activity is immeasurable.
Sub-Saharan Africa refers to the diverse landscape of more than 50 countries of Africa, which are south of the Sahara Desert. There are over nine million square miles of valleys, plateaus, and mountains in this region of Africa. Because of the prevalence of plateaus, Africa has been nicknamed the “continent of plateaus”. Between the plateaus, there are steep slopes, or escarpments. This continent has the highest overall elevation because of the plateaus it has. This area is mountainous with such mountains as the Atlas Mountains in the Northwest, Drakensburg Mountains and Mt. Kilimanjaro is the highest peak. The Great Rift Valley is also in this region. There are many rivers in this region, including the “Nile, Congo, Niger, and the Zambezi Rivers” (Physical Geography).
