Question

Quizplus · Accepted Answer

The seafloor magnetic pattern is parallel to and symmetric about mid-ocean ridges. This is due to the process of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges and the Earth's magnetic field at the time is recorded in the rocks as they cool and solidify. The polarity of the magnetic field reverses regularly over time, resulting in alternating patterns of magnetic stripes that are parallel to and symmetric about the mid-ocean ridges.
