the contintinental plate goes below the other and lava floating from the center of the earth creates a ridge
when two oceanic plates collide they create a deep-ocean trench, at deep-ocean trenches subduction occurs.
That is called subduction.
When two of Earth's oceanic plates collide, they can form a deep valley called a trench. Trenches are often found in subduction zones where one plate is forced beneath the other, creating a deep depression in the ocean floor.

the process by which new material is added to the ocean floor along the boundary between diverging plates.
Old ocean floor is destroyed and absorbed by the Earth at subduction zones, where tectonic plates collide and one plate is forced beneath the other. The remelting occurs beneath volcanic arcs, where the subducted crust melts and rises to the surface as magma, leading to the formation of new crust.
The continents and the ocean floor rest upon the plates.
