How do rocks along the central valley of the mid ocean ridge provide evidence for sea floor spreading?

because the scientists found that the farther the rocks the older the rocks were. so the youngest rocks were found near the mid-ocean ridge. this showed that sea-floor spreading took place.

The primary evidence is "magnetic striping": remnant magnetising by the Earth's magnetic field of the iron compounds in the basalt forming the ocean floor. The magnetic traces are parallel to the spreading-ridges, and their polarity reflect the field's periodic reversal. The further from the ridge, the older the stripes. The rock is imprinted with the magnetism as it cools below a certain point in being eruped along the ridge.
