Scientists can determine the age of the seafloor by watching the constant changing magnetic field of our planet. When it cools down, it records the magnetic field during its formation. The two parts of the oceanic plate are pulled apart, and magnetic stripes become older as they move away from the mid-ocean ridge. Hope that helps!
