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. Before technology like this, most people thought the ocean floor was flat and smooth. The West Coast of South America is a convergent boundary between the Nazca Plate and the South American Plate. These volcanoes typically produce ash and pyroclastic flows, as well as small amounts of andesitic lava. Your email address will not be published.

When two plates move towards one another, they form either a 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). This depends on the The Nazca Plate and the South American Plate are colliding. We'll look at different types of plates and their properties, including density and buoyancy, and how it affects the results of plate interactions. The collision (or convergence) of two of these platesthe continental South American Plate and the oceanic Nazca Plategave rise to the orogenic (mountain-building) activity that produced the Andes. In total, half a million people were killed by such natural disasters. Peru-Chile trench is formed due to subduction of Nazca plate. The seven major plates are the African, Antarctic, Eurasian, North American, South American, India-Australian, and the Pacific plates. This is because the oceanic lithosphere of the South American Plate is cooler and denser than that of the Caribbean Plate.

The subduction of the Nazca Plate is a slow and steady process that has been occurring for millions of years. It is composed of two types of lithosphere: the upper crust (where the continental land masses reside) and the thinner oceanic crust. 7. nature of the plates involved. Students determine what kind of boundary exists between the South American Plate and the Nazca Plate. Per year date the results provide the densest and most highly resolved geophysical of! As it descends, it drags against the overlying plate, causing both to fracture and deform. The Nazca plate is about 200 million years old and is one of the youngest tectonic plates on Earth. Where it meets the Caribbean Plate, it descends (subducts) beneath it. What is the moral lesson of at wars end by rony diaz? Due to the pull, it meets with the South American continental plate. 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. The Chile Rise, located on the southern side, is a divergent boundary between the Antarctic Plate and the Patagonian Plate, allowing magma to escape.
