Question

How does new ocean floor form at a mid-ocean ridge?

Answer 1

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

Answer 2

Answer:

magma rises between diverging plates, then cools and hardens.

Explanation:

a mid-ocean ridge forms at a  divergent plate boundary, where two ocean plates are moving apart. magma rises between the plates and become new ocean floor. the new floor the spreads away from the ridge.
