Which of the following scenarios best describes the activity present along the Mid-Atlantic Ridge? A. Magma is created by partial melting of crustal material as it sinks. B. Old sea floor is consumed as it is forced beneath another segment of sea floor. C. A plume of hot mantle material is pushing up against the crust, adding material to the crust to thicken it. D. Segments of sea floor slides past each other without creating or destroying crustal material. E. Magma wells up at the center of the ridge, which pushes the old sea floor apart as new sea floor is created.

Explanation / Answer

E. magma wells up at the center of the ridge. which pushes the old sea floor apart as new sea floor is created.

Mid Atlantic ridge is a mid ocean ridge, a diveregnt plate boundary or a constructive plate boundary where, new oceanic crust is getting formed. In the North Atlantic it seperates Euarsian and North American plate and in the South Atlantic it seperates African and South American plate.
