Paleomagnetism cycle
WebPlate tectonics and the geologic past. The extent to which plate tectonics has influenced Earth’s evolution through geologic time depends on when the process started. This is a matter of ongoing debate among geologists. The principal problem is that almost all oceanic crust older than about 200 million years has been obliterated by subduction.Some of the … WebMay 31, 2024 · Paleomagnetism also provides evidence to support theories in plate tectonics. Because the ocean floor is mostly composed of basalt, an iron-rich substance containing minerals that align with the magnetic field, they record the alignment of the magnetic fields surrounding oceanic ridges.
