Convergent Boundary
A convergent boundary is when two tectonic plates move toward or move apart from each other, they create mountain ranges, volcanoes, and/or earthquakes.
There are 3 different types of convergent boundaries :
1.) Oceanic-Oceanic
2.) Continental-Continental
3.) Oceanic-Continental

Oceanic-Oceanic Convergence
Oceanic-oceanic convergence is when two oceanic plates ram into each other, the plate that`s older, colder, and denser, bends and then slides down into the mantle. New crust is made then, as the magma breaks through and forms a volcano. Oceanic-oceanic convergence also makes deep-sea trenches.
Continental-Continental Convergence
When one continental plate and another continental plate collide, they crunch up. One plate slides downwards, while the other plate may form a mountain range. When this happens an earthquake may occur. The reason why volcanoes aren't created is because there is little or no sebduction.
Oceanic-Continental Convergent
When an oceanic plate covers a continental plate, the oceanic plate scrapes under the continental plate, drilling deep into a part of the mantle, called the subduction zone. Subduction zones along oceanic-continental plates, create deep-sea trenches. Trenches are common around the Pacific ocean because of subduction. High temperatures cause rocks to melt into magma as it goes beneath the continental plate. The new magma is forced into the upper plate, creating volcanoes.
