GinnyAnswer

Final answer:

Molten rock replaces the moving rock at mid-ocean ridges during sea-floor spreading, forming new oceanic crust.


Explanation:

As rock moves away from a mid-ocean ridge due to sea-floor spreading, it is replaced by molten rock. This molten rock forms new oceanic crust as it solidifies. Over time, the newly formed crust gets covered with layers of sediment which eventually turn into sedimentary rock.
