Paleomagnetic studies involve analyzing the magnetic properties of rocks to understand the historical changes in Earth's magnetic field. By examining the orientation of magnetic minerals within rocks, scientists can determine the latitude at which the rocks formed and track the movement of tectonic plates over geological time. These studies provide valuable insights into the Earth's geological history, including the formation of continents and the occurrence of past magnetic reversals. They also contribute to our understanding of plate tectonics, geological time scales, and the evolution of the Earth's magnetic field, which has implications for climate change and natural resources.
