Question

Quizplus · Accepted Answer

To determine the timescale on which the Earth's magnetic field reverses direction, one would study the magnetic stripes on the seafloor at spreading centers. These stripes record the Earth's magnetic field at the time that the rocks formed and can be used to determine the frequency and timing of magnetic field reversals.
