Line of evidences paleomagnetism
NettetTerms in this set (19) Paleomagnetism. ("ancient magnetism") is the study of Earth's ancient magnetism as preserved in rocks. When rocks form (a lava flow or mudstone, for example), certain minerals in the rock (like magnetite!) 'lock in' or preserve the magnetic field at the location and the time that the rock forms. NettetPaleomagnetic studies, the study of ancient magnetic fields, are based on one key fact. As certain rocks are formed, they store a record of the direction of earth's …

Continental drift was a theory that explained how continents shift position on Earth’s surface. Set forth in 1912 by Alfred Wegener, a geophysicist, and meteorologist, continental drift also explained why look-alike animal and ...
NettetThe mode and rates of tectonic processes and lithospheric growth during the Archean [4.0 to 2.5 billion years (Ga) ago] are subjects of considerable debate. Paleomagnetism may contribute to the discussion by quantifying past plate velocities. We report a paleomagnetic pole for the ~3180 million year (Ma) old Honeyeater Basalt of the East ...

NettetPaleomagnetism, polar wandering, and continental drift. Ironically, the final vindication of Wegener’s hypothesis came from the field of geophysics, the subject used by Jeffreys to discredit the original concept. The ancient Greeks realized that some rocks are strongly magnetized, and the Chinese invented the magnetic compass in the 13th century.
