Answer:
Mid-oceanic ridge and a ridge
Explaination:
The mid ocean ridge is where seafloor spreading takes place along a divergent plate boundary.
They are usually formed by plate tectonics with a depth of about 2,600 meters (8,500 ft) and rises about two kilometers above the deepest portion of an ocean basin.
A rift represents a lowland region that forms where Earth's tectonic plates move apart, or rift. An example is the Rhine rift valley in Germany.
Answer:
Japan is situated in a volcanic zone on the Pacific Ring of Fire. Most of the earthquakes following that occurred in Japan happened because of a destructive plate boundary. This is when continental and oceanic plates collide and the heavier, more dense oceanic plate sinks underneath the continental one.
Earthquakes are most common at tectonic plate boundaries where different plates meet called fault line. They were thought to not occur anywhere but near plate boundaries.
