Web27 okt. 2024 · 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. WebDescribe how you are interacting with each of Earth's spheres: atmosphere, hydrosphere, lithosphere, and biosphere. 2) Answer each of the following questions about the Earth's relationship with the Sun. a) Which two things are provided to the Earth by the Sun? ight and head are provided to the Earch the can . b) Research convection currents.
WebConvection currents also stress the lithosphere above, and the cracking that often results manifests as earthquakes. According to the theory of plate tectonics, the … WebConvection currents occur when temperature differences cause fluid material to move.The heat in the Earth’ s core powers convection currents inside Earth.

WebThe hypothesis of convection currents suggests that flow in the mantle is induced by currents which drag and move the lithospheric plates above the asthenosphere. Convection currents rise and spread below divergent plate boundaries and converge and descend along convergent. WebThe mechanism by which tectonic plates move is still a subject of much debate among Earth scientists. The Earth is dynamic thanks to its internal heat, which comes from deep within …
