There are several, mainly, the Mediterranean, Suez Canal, the Red Sea, and the Indian Ocean.
Good morning, I will me glad to help you with this. Here are the three types of boundaries and the actions that occur in each one of them:
Divergent Boundary: This occurs when two tectonic plates move away from one another. New crust on torn edges of the plates are formed in this process.
Convergent Boundary: This occurs when two tectonic plates come together (and sometimes bend down in seafloor trenches). Mountain ranges are formed in this process.
Transform Plate Boundary: This occurs when two tectonic plates slide past each other. This can create a linear fault valley or a undersea canyon. (No magma is formed in this process, but the crust is damaged)
