Numerical calculations of the dynamical ellipiticity of the moon due to finite amplitude solid state convection indicate that convection could be the cause of the non-hydrostatic gravitational figure, but only if the lunar lithosphere is capable of resisting global scale deformation. Thus lithosphere is capable of resisting global scale deformation. Thus lithospheric inhomogeneities and surface loads could also contribute substantially to the disequilibrium of the gravity figure. The calculations also show that it is unlikely that the geometrical distortion is due to convection.
