Lithospheric convection currents
Web23 mei 2024 · Researchers have proposed three main reasons why the tectonic plates are moving. All of these reasons boil down to various forces that are creating the movement. … WebAnswer: The theory of plate tectonics suggests that the lithospheric plates move because of convection currents in the semi molten mantle. Explanation: Convection currents can be observed on the surface of a hot liquid. If there are minerals in the liquid that can solidify as they cool, the minerals are observed to form plate like structures.
