Convergent boundary. 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. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. [1]

When continental and oceanic plates collide, the thinner and more dense oceanic plate is overridden by the thicker and less dense continental plate. The oceanic plate is forced down into the mantle in a process known as \"subduction.\" As the oceanic plate descends, it is forced into higher temperature environments. At a depth of about 100 miles (1...
The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate. The Andes Mountain Range of western South Ame...
Effects of a convergent boundary between an oceanic and continental plate include: a zone of earthquake activity that is shallow along the continent margin but deepens beneath the continent; sometimes an ocean trench immediately off shore of the continent; a line of volcanic eruptions a few hundred miles inland from the shoreline; destruction of oc...
Fragments of crust or continent margin sediments might be caught in the collision zone between the continents, forming a highly deformed melange of rock. The intense compression can also cause extensive folding and faulting of rocks within the two colliding plates. This deformation can extend hundreds of miles into the plate interior.
Jun 10, 2024 · At an ocean-ocean convergent boundary, one of the plates (oceanic crust and lithospheric mantle) is pushed, or subducted, under the other (Figure 4.6.1 4.6. 1). Often it is the older and colder plate that is denser and subducts beneath the younger and warmer plate. There is commonly an ocean trench along the boundary as the crust bends downwards.
Another form of convergent boundary is a collision where two continental plates meet head-on. Since neither plate is stronger than the other, they crumple and are pushed up. This can lead to the formation of huge, high mountain ranges such as the Himalayas. When two tectonic plates slide past each other, the place where they meet is a transform ...
Feb 15, 2021 · Convergent Plate Boundaries. Convergent Plates move together and collide so you have compressional forces. They are associated with active margins —locations where mountain building is occurring, resulting in numerous earthquakes and andesite (explosive) volcanoes. A subduction zone is a plate boundary along which one plate of the Earth’s ...

The melted rock rises into and through the overlying plate as magma, often forming a chain of volcanoes parallel to the plate boundary. Powerful earthquakes are common along these boundaries. The Pacific Ring of Fire is an example of a convergent plate boundary. Two plates sliding past each other forms a transform plate boundary. One of the ...
