The heat energy that powers tectonic activity on the surface of Earth originates deep in Earth's core.How does this energy move from the core to the surface?

Question

Quizplus · Accepted Answer

Heat energy from the core is transferred to the surrounding solid lower mantle through conduction. This heat is then transported to the surface through convection currents that move in the upper mantle. These movements in the mantle are responsible for tectonic activity and the movement of the Earth's plates.
