Subduction
Explanation:
When an oceanic crust collides with the edge of a continent, subduction occurs with a host of physical geological structures.
This kind of margin is called a convergent margin.
- The earth is broken into series of slabs called lithosphere.
- When an oceanic crust collides with the edge of a continent, the oceanic crust will subduct and go under the continental crust into the asthenosphere.
- The continental crust is less dense and buoyant.
- Oceanic crust is denser than the asthenosphere below and it will sink into it.
