On Convergent Plate Boundary?

At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

What happens at a convergent tectonic plate boundary?

If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.

Where is a convergent plate boundary?

In the ocean basins, convergent plate margins are marked by deep trenches in the sea floor. The convergent plate boundaries that occur on continents are the collisional mountain belts. Following are 3 examples of different tectonic settings of convergent plate boundaries.
