Mantle convection is the primary mechanism to remove heat from terrestrial planets, thus controlling the thermal evolution of terrestrial planets. Heat transfer and the planform of mantle convection depend critically on the rheology of planetary mantles [Christensen, 1984; Jaupart and Parsons, 1985; Moresi and Solomatov, 1995].

Simple Rayleigh-Taylor type convection. Linear viscous rheology. No-slip boundary conditions on both sides. Average resolution is ~100km. Ran over a Mantle convection is the slow creeping motion of Earth's rocky mantle caused by convection currents carrying heat from the interior of the earth to the surface. It is one of 3 driving forces that causes tectonic plates to move around the Earth's surface. Usability and extensibility: Simulating mantle convection is a difficult problem characterized not only by complicated and nonlinear material models but, more generally, by a lack of understanding which parts of a much more complicated model are really necessary to simulate the defining features of the problem.

It is thought that heating of the mantle by the core creates convection cells in which hot mantle material rises, cooling as it goes, toward the crust until it reaches less dense material, at which point it spreads out then descends.

Based on Hager and O'Connell's solution to mantle flow equations, the stresses induced by mantle convection are determined using the density and DiVA.

This flow, called mantle convection, is an important method of heat transport within the Earth. Mantle convection is the driving mechanism for plate tectonics, which is the process ultimately responsible for producing earthquakes, mountain ranges, and volcanos on Earth. Mantle convection is also important on Venus and Mars. Mantle rocks are able to deform in a fluid-like manner over times in excess of about 1 million years and from a geological perspective the mantle is therefore a highly dynamic part of the Earth. Mantle convection is the process by which the excess heat in the Earth's deep interior is transferred to its surface through the fluid-like motions of the rocks in the mantle. Here, we present global mantle convection calculations that result in a mobile lithosphere featuring dynamically derived plate boundaries exhibiting a contrasting superficial structure which Mantle convection and plate tectonics are one system, because oceanic plates are the cold upper thermal boundary layer of the convection. The slow motion of plates and the mantle is powered by radio-genic heating and by the slow cooling of our planet over its 4.5-billion-year history (4).
