The 2004 Indian Ocean tsunami was triggered by a megathrust earthquake at a convergent boundary. Three convergent boundaries Continental plate and an oceanic plate convergeA continental plate converging with an oceanic plate creates a subduction zone. Off the coast of Alaska, the Pacific Plate is ...
analogous to modern divergent and convergent plate boundary processes. Our results provide direct evidence for lateral plate motions in the late Neoarchean, and arguably the operation of plate tectonics, albeit with warmer than average Phanerozoic subduction geotherms. Further, we surmise that plate tect...
con·ver·gent plate boundary (kən-vûr′jənt) A tectonic boundary where two plates are moving toward each other. If the two plates are of equal density, they usually push up against each other to form a mountain chain. If they are of unequal density, one plate usually sinks (...

Convergent plate boundaries like that between the present western Pacific and eastern Asia constitute a special type related to subduction in provinces of mantle superplumes. The West Pacific-type convergent boundaries may reach thousands of kilometers across and consist of several structures that ...
If two tectonic plates collide, theyform a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to par...
underneath the other plate. The results of this tectonic collision are similar to those involving oceanic and continental plates. A deep trench is formed on the seafloor. For example, the formidable Marianas Trench has been formed by the subduction of the Philippine Plate under the Pacific Plate....
In this type of convergent boundary, a powerful collision occurs. The two thick continental plates collide, and both of them have a density that is much lower than the mantle, which prevents subduction (there may be a small amount of subduction, or the heavier lithosphere below the continental...
divergent, and side-slipping. Japan and the Aleutian Islands are located on convergent boundaries where the Pacific Plate is moving beneath the adjacent continental plates—a process known as subduction. The San Andreas Fault system in California exemplifies a side-slipping boundary where the Pacific ...
The characteristics that describe convergent boundaries are that mountain ranges are typically found at this boundary, as well as powerful earthquakes from the plates colliding. What are examples of convergent boundaries? Some examples of convergent boundaries are: Subduction of the Nazca Plate...
