WebThe concept of paleomagnetism because it was a very good explanation of the processes including the magnetic poles , movement of the ocean floor , and the idea of plate tectonics . 4. Did the discovery of magnetic reversals change the way scientists view the movement of continents in the late 1960’s? WebDec 11, 2024 · Paleomagnetism is a valuable tool for paleo plate tectonics because it can be used to reconstruct the motion of tectonic plates. By studying the magnetic properties of rocks, geologists can determine the direction and intensity of the Earth’s magnetic field at the time when the rocks were formed.

WebFeb 10, 2024 · Paleomagnetism is the study of the record of the earth’s magnetic field with the help of magnetic fields recorded in rocks, sediment, or archaeological materials. The polarity of the Earth’s magnetic field and magnetic field reversals are thus detectable by studying the rocks of different ages. WebThe Editors of Encyclopaedia Britannica. Although this has yet to be proven with certainty, most geologists and geophysicists agree that plate movement is caused by the convection (that is, heat transfer resulting from the movement of a heated fluid) of magma in Earth’s interior. The heat source is thought to be the decay of radioactive elements. cga means in therapy
