The deeper you go into the Earth the higher the temperature and pressure. The third edition of this widely acclaimed textbook provides a comprehensive introduction to all aspects of global tectonics, and includes major revisions to reflect the most significant recent advances in the field. The formation of some of the youngest oceanic crusts in the world occurs as a result of a diverging plate motion. 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. There is much debate over whether the South American Plate is oceanic or continental in nature. Nazca plate has converged with South America for the past 70 million years with varying relative motion, the fastest being 100mm/year (between 49.5 to 42 million years ago, and since 26 million years ago), and at slower times 50-55mm/year.

The seven major plates are the African, Antarctic, Eurasian, North American, South American, India-Australian, and the Pacific plates. Who makes the plaid blue coat Jesse stone wears in Sea Change? Convergence can involve to oceanic plates, an oceanic plate & continental plate, or two continental plates. This forms an accretionary wedge (or prism), where layers of the deformed and metamorphosed sediments and ocean crust are thrust onto the South American Plate along faults or thrust planes adding to the size of the continent. At the surface, the topographic expression is commonly an oceanic With an area of 76 million km2, it is the Earth's second largest tectonic plate, behind the Pacific Plate. 3.

The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the oceanic crust of the North American Plate. The signal is global in scope, with a posi- tively . side. This lesson will explain what the continental crust is, describe its composition and properties, and discuss the history of how the continental crust was formed. The molten rock, or magma, that is created as the Nazca Plate is subducted is being forced upward into the Earths crust. Each year, a subducting force of 8 cm is generated beneath the west coast of South America by the Nazca Plate. A teacher walks into the Classroom and says If only Yesterday was Tomorrow Today would have been a Saturday Which Day did the Teacher make this Statement? Because of this, the margins of the plates are always interacting with one another. Fractures paralleling the coast are likely related to the opening of the Atlantic Ocean as South America drifted away from Africa, starting about 130 million years ago. The new data indicates that 85% of fresh basalts and gabbros were used, and 15% of all basalts had been fully metamorphosed.

The western coast of South America is a very good example of an oceanic to continental convergent boundary where the Nazca plate is colliding (and being subducted beneath) the South. Quick Tips. This process, called subduction, occurs at the oceanic trenches. It is composed of basalt and mafic rocks that are high in iron, magnesium, and calcium. Some scientists believe that the Nazca Plate is divergent, while others believe it is convergent. More ra rely, ocean trenches can be formed when two plates carrying oceanic crust meet.
