Answer:

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.
