Convection comes from mantle
WebComputer Model of Mantle Convection. Scientists study mantle convection, or the flow of hot rock in the Earth's deep interior, in order to better understand how this flow shapes the surface of the Earth. When a solid, liquid, or gas is heated, it expands, becomes less dense, and rises. When it cools, it contracts, becomes more dense, and sinks. WebThe convection of the Earth's mantle is a chaotic process (in the sense of fluid dynamics), which is thought to be an integral part of the motion of plates. Plate motion should not be confused with continental drift which applies purely to the movement of the crustal components of the continents.
