Paleomagnetism plate movements

WebDec 18, 2024 · Paleomagnetism explains the history of direction and strength of Earth’s magnetic field and the past location of the tectonic plates and applies to the movement of the tectonic plate fragments. Explanation: The magnetic field in rocks, sediments and archeological materials are observed using Paleomagnetism. 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.
