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.
Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.
New ocean floor is formed at mid-ocean ridges, which are underwater mountain ranges where tectonic plates move apart, allowing new magma to rise up and solidify into new crust. This process is known as seafloor spreading.
...at constructive plate margins / boundaries.hence the term contructive, new crust is "contructed" here.(and destructed at a destructive plate margin / boundary / subduction zone.)
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.

Sea Floor Spreading!
Ocean floor is primarily created at mid-ocean ridges where tectonic plates move apart, allowing magma to rise from the mantle and solidify as new oceanic crust. This process, known as seafloor spreading, results in the formation of new crust that eventually spreads away from the ridge and contributes to the growth of the ocean floor.
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.
