A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction .
Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This ...
The Nazca plate or Nasca plate, [2] named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The ongoing subduction , along the Peru–Chile Trench , of the Nazca plate under the South American plate is largely responsible for the Andean orogeny .
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
There are three types of plate boundaries to consider in the context of interplate earthquake events: [4] Transform fault: Where two boundaries slide laterally relative to each other. Divergent boundary: Where two boundaries move apart. Convergent boundary: Where one plate moves towards, and potentially subducts beneath, another plate.
The most significant areas of thrust tectonics are associated with destructive plate boundaries leading to the formation of orogenic belts. The two main types are: the collision of two continental tectonic plates (for example the Arabian plate and Eurasian plate , which formed the Zagros fold and thrust belt ) and collisions between a continent ...
[18] [19] The bottom of the trench marks the boundary between the subducting and overriding plates, known as the basal plate boundary shear [20] or the subduction décollement. [2] The depth of the trench depends on the starting depth of the oceanic lithosphere as it begins its plunge into the trench, the angle at which the slab plunges, and ...
When a large portion of dense materials was removed under the tectonic plate at this location, the remaining portion of the crust and lithosphere underwent a rapid uplift forming this mountain range. In geodynamics , delamination refers to the loss and sinking (foundering) of the portion of the lowermost lithosphere from the tectonic plate to ...
