Question

Quizplus · Accepted Answer

A mid-ocean ridge is a long chain of mountains that is located at a divergent boundary where tectonic plates move apart. It is where new oceanic lithosphere is created by magma rising from the mantle and solidifying into rock. Therefore, option B is the correct statement about a mid-ocean ridge. Options A and E are incorrect because deep ocean trenches, not mid-ocean ridges, are the deepest parts of the ocean basin and sites of the largest and most devastating earthquakes. Option C is partially correct, as mid-ocean ridges do involve the creation of new oceanic lithosphere; however, not through the remelting of old lithosphere. Option D is incorrect because mid-ocean ridges are not typically sites of explosive volcanic eruptions.
