Question

Magnetic reversals provide evidence for seafloor spreading, which is a crucial part of the theory of plate tectonics. The magnetic properties of rocks on the ocean floor provide a record of the Earth's magnetic reversals, which can be used to determine the age of the rocks and the rate at which the seafloor is spreading. This evidence supports the idea that the Earth's lithosphere consists of tectonic plates that move around and interact with each other.
