As the volcanic material moves away from the Mid Ocean Ridge, it cools (which makes it denser); it forms the large 'Giants Causeway" type of polygon rock forms; once it has passed through the Curie point, it preserves a record of the magnetic field as is was when the rock cools.

How does seafloor spreading results in new oceanic crust?
As the seafloor spreads apart, magma from the mantle inside the earth bubbles up to the ocean and hardens in the cool temperatures, producing new oceanic crust
What happens at hydrothermal vents?
Seawater seeps into the ocean floor through cracks in the crust
