WebOct 3, 2024 · What is paleomagnetism quizlet? Paleomagnetism. the study of changes in Earth’s magnetic field, as shown by patterns of magnetism in rocks that have formed over time. How does paleomagnetism and seafloor spreading explain plate tectonics? The symmetric banding is the result of seafloor spreading on both sides of a mid-oceanic ridge. WebPaleomagnetism is the study of the ancient magnetic field of both rocks and the Earth as a whole. Paleomagnetism has provided very strong quantitative evidence for polar wander and continental drift. It is interesting to note, however, that although this evidence was published in the late 1950s, the concept of continental drift did not gain widespread …

What discovery provided strong support for continental drift theory?
WebThe alignment of a magnetic mineral in a cooled igneous rock points to the magnetic north pole, and the dip of the mineral reveals how far the rock formed from the pole. The paleomagnetic evidence revealed that the magnetic poles also had different locations relative to the continents than they do today. Magnetic minerals on one continent do ...
