![]() ![]() The tectonic activity at this convergent boundary has led to the formation of the volcanic Cascade Mountain Range.Ī convergent boundary might also feature two oceanic plates. Here the oceanic plate of Juan de Fuca is subducting beneath the North American continental plate that is moving in a westward direction. The formation of volcanoes at such sites is explained below as an answer to the question: How Do Volcanoes Form At Convergent Boundaries?Īn example of this type of convergent boundary is the Washington-Oregon coastline of the US. Deep oceanic trenches are produced in the process and the subduction activity might lead to earthquakes or volcanic eruptions. The thinner and denser oceanic plate usually subducts below the thicker and less dense continental plate. ![]() When a continental and an oceanic plate collide at the convergent boundary of the two plates, subduction zones often develop. There are three types of convergent boundaries depending on the nature of the tectonic plates converging with each other. Some or all of these activities happen at the convergent boundaries: subduction of the denser plate underneath the less dense one, melting of parts of the subducted plates, plate collision, faulting and folding, crustal deformation, magma generation, volcanic eruptions, and earthquakes. What Happens At A Convergent Boundary?Ĭonvergent boundaries are highly unstable areas of the lithosphere of the Earth. Now that we know what tectonic plates mean, we can easily answer the question of what a convergent boundary is.Ĭonvergent boundaries, also referred to as destructive plate boundaries, are locations on the lithosphere where two or more tectonic plates move towards each other leading to high levels of tectonic activities. What Is A Convergent Boundary? Where Are Convergent Boundaries Located? It was these tectonic movements that gave birth to the continents we see today after the continental plates broke away from the supercontinent of Pangaea. The tectonic plates of the lithosphere are not static in nature but are constantly moving towards and away from each other. The tectonic plates are of two types: the oceanic plates, and the continental plates. The lithosphere of the Earth that includes the crust and the uppermost mantle is not continuous in nature but is subdivided into several pieces called tectonic plates. To answer the question “What Is A Convergent Boundary?”, we first need to understand the meaning of tectonic plates. ![]()
