The Andes Mountain Range of western South America is another example of a convergent boundary between an oceanic and continental plate. Some of the most familiar ocean trenches are the result of this type of convergent plate boundary.The Peru-Chile Trench off the west coast of South America is formed by the oceanic crust of the Nazca plate subducting beneath the continental crust of the South American plate. Highly resolved geophysical image of an active subduction orogen, the border between South! Collision of continental and oceanic plates or ocean-continent convergence (formation of continental arc s and fold mountains). "[2] As a result, the eastward-moving and more dense Nazca Plate is subducting under the western edge of the South American Plate, along the continent's Pacific coast, at a rate of 77mm (3.0in) per year. The convergent boundaries correspond to subduction zones where an oceanic plate is involved. Tectonic feature of each sequence developed in the Caribbean region; however, a direct cause and effect from only the late Tertiary can be seen in terms of convergent motion of South America and North America, resulting in north south compression across the northern and southern boundaries of the Caribbean (Ladd, 1975). plate. 5 Which plate does most of North America sit on?

Southeast of Florida, the Caribbean Plate is sliding east-northeast about 0.8 inches (2 centimeters) per year relative to the North American Plate. One trench in South America is the Peru-Chile Trench . Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. Are the Pacific Plate and North American Plate in water? Is the Arabian Plate oceanic or continental? This book can also be used as an up-to-date reference at universities in both undergraduate and postgraduate levels. The subduction of the Nazca Plate beneath South America is responsible for the Andes Mountains.

Lscar erupted ash and pyroclastic flows in 1993 and was still active in 2012. In addition to their east-west (strike-slip) motion, the plates also acquired a north-south component of convergence, leading . This compression is causing the Nazca Plate to buckle and fold, creating the Andes Mountains. It is viscous, trapping gases as it rises. The Ring of Fire is a string of volcanoes and sites of seismic activity, or earthquakes, around the edges of the Pacific Ocean.Roughly 90% of all earthquakes occur along the Ring of Fire, and the ring is dotted with 75% of all active volcanoes on Earth. The South American Plate and the Nazca Plate are close relatives. Due to the subduction of the Nazca plate and the uplift of the continental crust of the South American plate the Andes Mountain range has formed on the western coast of South America.

More ra rely, ocean trenches can be formed when two plates carrying oceanic crust meet. The Atlantic Coastal Plain is covered by sedimentary layers of the modern passive continental margin. It is the seventh-largest tectonic plate, and it currently moved in a north-northwest direction. The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate.The East Pacific Rise is a mid-ocean ridge that runs through the eastern Pacific Ocean and separates the Pacific plate from the North American . In this lesson, you'll read about the composition and life cycle of this oceanic crust. Today, the Pacific Plate, along with the Pacific Ocean Basin, is shrinking. It is named after the Nazca Desert, which is located in southern Peru. The oceanic. There is a sequence composed of four periods of contrasting relative motion starting in Late Triassic that describes the relative motion of South American plate away from North American plate (Ladd, 1975).

Sn has a relatively low velocity of about 4.5kmIs and is not observed at distances greater than 16" in this part of the plate. Shell of the minor plates include the Arabian, Caribbean, Nazca, and Scotia.! This crustal shortening increases the vertical thickness whilst reducing the width of the lithosphere in the collision zone (imagine a car hitting a solid wall) and so produces the fold mountains of the Andes. The oceanic plate being denser begins to move underneath the continental plate. All other trademarks and copyrights are the property of their respective owners.

Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. This was the largest earthquake ever recorded in Earths history which lasted 10 minutes in length. South American plate is a relatively large sized plate located below the continent South America. According to Britannica the trench is about 3,666 miles long and gets as deep as 26,460ft. It is composed of basalt and mafic rocks that are high in iron, magnesium, and calcium. The molten rock, or magma, that is created as the Nazca Plate is subducted is being forced upward into the Earths crust.
