usually from lava sinking to ocean floor and cooling.
New rock is added to the ocean floor by the process of seafloor spreading, in which the magma is pushed out of the mantle, and is cooled by the water. Creating a new layer of hard rock.
Sea- Floor Spreading molten material erupts through the valley that runs along the center of some mid-ocean ridges. This material hardens to form the rock of the ocean floor. Mid-ocean ridges an undersea mountain chain where new ocean floor is produced.
This sounds like the mid ocean ridge. This is where the plates are moving apart and magma wells up to form new rock.
New floor forms and spreads from mid-ocean ridges
as it spread away from a mid-ocean ridge, the sea floor carries with it a record or magnetic reversals. i hope this answer would be correct :) also, when the magma rises through fractures in the sea floor at the mid-ocean ridge, the magma cools and forms new rocks. this new rock takes place of the old rock and the old rock gets pulled away.
are equal in width and polarity
Molten rock at mid-ocean ridges is the result of sea-floor spreading. WRONG

the process by which new material is added to the ocean floor along the boundary between diverging plates.
those located at the fault in the bottom of the ocean because it is a volcano and produces new rock everytime the lava cools.
Ocean floor
New ocean floor is created at mic-ocean ridges which are divergent plate boundaries.
sedimentation
Sea Floor Spreading!
New material forms on the ocean floor of the mid-ocean ridge due to plate tectonics and volcanic activity. Volcanic eruptions deposit cooled magma on the ocean floor.
