Convection currents within the asthenosphere
WebMar 2, 2024 · Convection currents, that occur within the molten rock in the mantle, act like a conveyor belt for the plates. Tectonic plates move in different directions. The friction between the convection current and the crust causes the tectonic plate to move. The liquid rock then sinks back towards the core as it cools.

WebSep 12, 2024 · Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material. Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy.
