“Describe how the magnetic patterns found in undersea rocks provide evidence for the process of seafloor spreading. Explain how changes in Earth's magnetic field polarity are recorded in undersea rocks and what this reveals about the movement of oceanic crust over time. If a symmetrical pattern of magnetic stripes is observed on either side of a mid-ocean ridge, what can you infer about the rate and direction of plate movement?”
