How does paleomagnetism prove continental drift?

WebEvidence supporting the hypothesis. The strikingly similar Paleozoic sedimentary sequences on all southern continents and also in India are an example of evidence that supports continental drift. This diagnostic sequence consists of glacial deposits called tillites, followed by sandstones and finally coal measures, typical of warm moist climates.

WebIn other words, the paleomagnetic evidence appears to support the arguments for continental drift. POLAR “WANDERING” CURVES We have learned that rock samples containing magnetic minerals (commonly magnetite) provide information (direction and inclination) on where they were formed relative to the north magnetic pole. WebIn the 1950s, paleomagnetic evidence supporting continental drift became available. When rock is in a molten state, the magnetic particles it contains are free to move around, and they orient themselves toward the Earth's magnetic poles. Once the rock cools and hardens, the orientation of the individual magnetic particles becomes fixed. WebApr 6, 2024 · In this study, we report a new paleomagnetic pole of 29.8°N, 180.7°E (A 95 = 5.7°) obtained from the ∼170 Ma Yeba Formation in the Lhasa terrane, which satisfies all seven criteria proposed by Van der Voo and Meert et al. . Our new paleomagnetic result indicates that the Lhasa terrane was located at ∼14.4 ± 5.7°N at ∼170 Ma. thin black bedside table

WebMay 20, 2024 · In the early 20th century, a scientific theory called continental drift was proposed about this migration of the continents. That theory was initially ridiculed, but it paved the way for another theory called plate tectonics that scientists have now accepted to explain how Earth’s continents move.
