Answer

True Explanation 1. Understanding the Concept of Plate Tectonics The Earth's lithosphere is divided into tectonic plates that float on the semi-fluid asthenosphere beneath them. These plates are moved by convection currents in the mantle, which are driven by the Earth's internal heat energy. 2. Role of Convection Currents Convection currents are caused by the heat from the Earth's core creating a cycle of rising and sinking material in the mantle. This movement acts as a conveyor belt, driving the motion of tectonic plates on the Earth's surface. 3. Evaluating the Statement Given the understanding that convection currents in the mantle, powered by the Earth's internal energy, are responsible for the movement of tectonic plates, the statement "The Earth's internal energy moves the plates by convection currents" is accurate.
