How did magnetic anomalies contribute to the development of the plate tectonics theory?
They showed that Earth's magnetic field is uniform and unchanging over time.
They revealed symmetrical magnetic stripes on the ocean floor indicating seafloor spreading.
They proved that magnetic fields have no relation to geological structures.
