Question

Quizplus · Accepted Answer

Paleomagnetic evidence for seafloor spreading is primarily found in basaltic rocks, which contain iron-rich minerals that align with Earth's magnetic field at the time of their formation. As new basaltic rocks are formed at mid-ocean ridges and move away from the ridge, their magnetic orientation provides evidence for the direction and rate of seafloor spreading. Ocean floor sediments and continental sediments may also contain paleomagnetic evidence, but it is not as direct or reliable as that found in basaltic rocks.
