This is because the oceanic lithosphere of the South American Plate is cooler and denser than that of the Caribbean Plate. The South American Plate is a continental tectonic plate. The Andes are a continental arc (narrow, continental volcanic chain) formed due to the volcanism above the subduction zone. Offers a detailed, informative and lively discussion on four of the Earth but affect! Or subduction zones occur when two plates collide and push upwards to form a trench and volcanoes wide. The seven major plates are the African, Antarctic, Eurasian, North American, South American, India-Australian, and the Pacific plates.

Does the North American Plate consist of an oceanic lithosphere? plate is exemplified by the North American Plate, which includes North America as well as the oceanic crust between it and a portion of the Mid-Atlantic Ridge. Lscar erupted ash and pyroclastic flows in 1993 and was still active in 2012. (Weber et al, 2001). An example would be the convergence of the oceanic Nazca Plate The subduction of the Nazca Plate is also responsible for the volcanoes in the Andes Mountains. The rift split the super-continent to form a narrow ocean basin. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.

Gone though reversals if you 've ever flown to Europe, you know that it 's moving forcing. 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 Nazca plate that lies in the eastern Pacific ocean is pulled towards the South American continent. This tectonic collision developed a composite transform-convergent margin characterized by normal and strike-slip faults that formed extensional/pull apart basins along the western margin of Peru.
