The collisions of plates occur at "convergent boundaries". Convergent boundaries include "subduction zones" (where one goes under the other) and "continental collisions".
Please see the related link for more information on the topic.
convergence
When two tectonic plates collide and one plate is forced beneath the other, this process is known as subduction. This typically occurs at convergent plate boundaries, leading to the formation of deep ocean trenches and volcanic arcs. The subducting plate melts as it descends into the mantle, which can result in volcanic activity and the creation of mountain ranges.
When two plates collide one pushes the other one down. Then the magma goes through the gaps between the plates and then the volcano erupts. Volcanoes can also erupt by the plates spreading apart.
Mountains form where continental and oceanic plates collide by the actions of the plates upon one another. Often one plate pushes up and over the other one, and the upper one creates a row of mountains.
The more dense plate subducts (goes under) the less dense plate. For example if continental and oceanic crust collide oceanic crust will go underneath the continental.
The subduction zone.
subduction boundrary. thanks for looking :)
The plates in the earth collide and one goes under the other
Subduction.
convergence
the contintinental plate goes below the other and lava floating from the center of the earth creates a ridge
Two tectonic plates collide, one goes under and the other goes over. Usually this forms an earthquake and is how most mountains are formed eg: the great dividing range. :D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D:D
Folded mountains form when tectonic plates collide and the crust is compressed and folded due to the immense pressure. The plates are not pushed down, but rather collide, causing the crust to buckle and fold upward to form mountains.
Best Answer:When two plates carrying oceanic crust collide, the resultis that one goes underneath the other - probably causinga tsunami - or an underwater earthquake.
The active one (the one that goes back to an active oceanic ridge).
When two plates collide directly (versus sliding along each other) they typically form a mountain range. For example, the Himalayan Mountains are are formed by the collision of the Eurasian Plate and the Indo-Australian Plate. As John McPhee says in "Annals of the Former World", the most amazing thing is that the summit of Mount Everest, the worlds tallest mountain, is marine limestone.
