Convection of molten material
WebA 2D model of laser melting consisting of heat transfer, hydrodynamic flow, surface tension, and a free surface motion was established. A physical field simulation of the laser melting process was performed, and the effect of steady magnetic field parameters on the internal flow and temperature fields of the melt pool was analyzed and validated by experiments. … WebMolten rock that appears on the atmosphere is called lava, and it reaches the surface through volcanic processes. “ Magmatism and Volcanism ” By Woudloper, CC BY-SA …

The liquid inside the earth moves in a circular motion and in this way heat transfer takes place. The hotter liquid moves up and the cold liquid takes place of the hotter particles and it looks exactly like a circular movement of liquids.
Webthe force that causes most of the plate movement is thermal convection, where heat from the earths interior causes currents of hot rising magma and cooler sinking magama to flow, moving the plates of the crust along with them. 14. an american geologist stated that a hot molten material from the mantle rises to the mid ocean ridge.
