Figure 1From: Towards scaling laws for subduction initiation on terrestrial planets: constraints from two-dimensional steady-state convection simulationsTemperature (left) and stress fields (right) of a steady-state convective cell. Color scale goes from high (red) to low (blue). The lid is defined by an isotherm T L , and the interior temperature T i is found by averaging the temperature of the convecting interior excluding boundary effects. For scaling purposes, the lid slope λ and rheological sublayer thickness δ rh is taken at mid-width, whereas lid thickness δ lid is extrapolated to the edge from the lid slope in the middle.Back to article page
