Plate Tectonics

Convergent Boundaries

In plate tectonics there are three types of boundaries; divergent boundaries, convergent boundaries and transform boundaries.

What are convergent boundaries?

Convergent boundaries occur when two or more tectonic plates are move toward one another and some colliding. There are several geological activities that could happen at convergent boundaries. When two tectonic plates converge, the denser plate slides underneath the other. This process is called subduction. Active volcanoes often form in the subduction zones. Mountain ranges are often formed when two continental tectonic plates collide. Below are examples of what happens at convergent boundaries.

If an oceanic tectonic plate meets a continental tectonic plate, then the oceanic plate will slide under the continental plate and the oceanic crust will become part of the Earth's mentle.

If two oceanic tectonic plates converge, then denser plate is subducted under the other forming a deep sea trench.

Examples of convergent boundaries of tectonic plates

The Nazca Plate is an example of a convergent boundary sliding below the South American Plate. The Marianan Trench in the western Pacific Ocean is where the Pacific Plate converges with the Philippine Plate. The Himalayas and the Tibetan Plateau are among the most dramatic effects of convergent boundaries of tectonic plates.
