Answer:
6. it's called divergent boundary where 2 plates are moving apart
7. it's called convergent boundary where 2 plates moves towards each other
8. in this case it undergoes subduction process where it's the bending of the crust towards the mantle. it is also considered as you know convergent boundary. and in subduction process in oceanic crust the trench is formed or also called as the submarine valleys, where ocean trenches are the deepest part of the ocean
9. its called the transform fault boundary where it is a boundary produced when two plates slide past one another. ex of transform fault boundary is the san andreas fault where is bounded by the North american plate and the pacific plate
