Short summary
The Earth's surface is characterized by numerous geological processes, formed throughout the Earth's history to present day. The interior (mantle), on which plates rest, undergoes convection motion, generating stresses in the lithosphere plate and also causing the plate motion. This study shows that shallow density heterogeneities in the upper 300 km have a limited influence on the modeled horizontal stress field as opposed to the resulting topography, giving the importance depth sampling.
