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:
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
When tectonic plates collide and form a convergent boundary, their interaction can produce earthquakes, volcanic activity, underwater trenches and mountain formations. Any resulting geologic events on the Earth's surface are determined by the type of tectonic plates involved in the collision: oceanic crust, continental crust or a combination of both.Full Answer >
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 >
Cross-country skiing involves attaching smooth, flat skis to one's boots and using a gliding motion while pushing with ski poles to slide on top of the snow. Nordic cross-country skiing, the more common variety, requires participants to kick straight forward and glide while their bodies are in a forward-leaning position. Skate skiing, another variant, requires skiers to push their skis forward in a v-shaped pattern.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 >
