A convergent plate boundary occurs when a collision of tectonic plates causes one plate to slide over the top of another. There are three examples of convergent plate boundaries that occur as the result of continental and oceanic plate convergence:Know More
Continental vs. Oceanic Convergence When a continental plate and oceanic plate collide, the more buoyant continental plate slides atop the oceanic plate, creating a subduction zone that features deep ocean trenches and volcanic mountains.
Oceanic vs. Continental Convergence When two oceanic plates collide, whichever plate is older (and thus denser) will be covered by the other, newer plate. These collisions result in the creation of volcanic mountains that can surface above the ocean as small island chains.
Continental vs. Continental Convergence When two continental plates collide, neither can "sink", because buoyancy is not a factor. Instead the pieces are crammed together, creating large mountains, such as the Himalayans.Learn more about Plate Tectonics
Convergent boundaries are defined as locations where tectonic plates collide with each other. The melting lithospheric material produces volcanoes, and the motion of the tectonic plates along the convergent boundaries leads to earthquakes.Full Answer >
Tectonic plates move horizontally past one another at transform boundaries in either strike-slip or aseismic motions. Earthquakes and tsunamis occur when the pressure locking plates in a strike-slip boundary releases suddenly. Volcanic activity, while common at convergent and divergent plate boundaries, is rare at transform borders.Full Answer >
An example of convergent evolution is the similar overall body structure of sharks and dolphins. The shark is a fish while the dolphin is a mammal, but their bodies have evolved to become similar. Another example is the adaptations for gliding found in both sugar gliders and flying squirrels.Full Answer >
The San Andreas Fault exemplifies a transform fault plate boundary. Transform fault boundaries consist of two plates sliding against each other in a horizontal motion.Full Answer >
