Lithospheric Plates The theory of plate tectonics proposes that the lithosphere is divided into eight major plates (North American, South American, Pacific, Nazca, Eurasian, African, Antarctic, and Indian-Australian) and several smaller plates (e. g. , Arabian, Scotia, Juan de Fuca) that fit together like the pieces of a jigsaw puzzle (Fig. What continents are around the Pacific Plate?

Read this lesson to learn what makes the African plate unique and how it's moving. 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). The movement of plates along a tectonic boundary is referred to as convergent movement. The Chile Rise, located on the southern side, is a divergent boundary between the Antarctic Plate and the Patagonian Plate, allowing magma to escape. This magma is causing the volcanoes in the Andes Mountains to erupt. The Nazca plate is an oceanic tectonic plate in the southeastern Pacific Ocean that shares both convergent and divergent boundaries, corners multiple triple junctions, contains three seamount chains, overrides four hotspots, and is responsible for the creation of the Andean orogeny (Figure 1).

These recurring events have increased our awareness of the destructive power of natural hazards and the major risks associated with them. As mentioned earlier, plates are always in constant motion. Also, this subduction zone generates enormous earthquakes. 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.

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). For example, the South American Plate moves at an average rate of about 3 centimeters per year. The jury is still out on this matter, and further research is needed to determine the true nature of the South American Plate. to the surface to stabilize the mantle, thus creating a Mountains are from when ether two Continental plates or a Continental and oceanic plates converge. 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. An oceanic plate (Cocos Plate) is subducted beneath another oceanic plate (Caribbean Plate) forming an oceanic trench to the west and active composite volcanoes that have coalesced into the isthmus of Central America.
