Does a planet need plate tectonics to develop life?

NettetSummary Absolute plate motions and intraplate stress both serve as tests of models for the forces acting on plate boundaries. Plate velocities relative to a presumedly fixed underlying mantle are calculated from the hypothesis that no net torque is exerted on the lithosphere. Intraplate stress is calculated by solving the equilibrium equations for thin … NettetI will add that some authors argue that at least some of the cycling between the atmosphere and interior may still occur on stagnant-lid planets, and more generally that the distinction between mobile-lid and stagnant-lid tectonics may not be as clear as it's often treated.Indeed, our modern mode of plate tectonics may not have set in until as … bank mestika batam https://dtsperformance.com
