Strength profiles for Mercury, Venus, Earth, and Mars calculated using a constant thermal gradient of 10 K/km and a constant strain rate of 10−17 s−1, under both dry (red lines) and wet (blue lines) conditions. Dashed lines indicate the influence of strain rate of 10−16 and 10−18 s−1, and dotted lines indicate the brittle strength in the presence of clay minerals. As plastic strength differs between crust and mantle, the strength profiles show a gap across the crust–mantle boundary (Moho) in case where deformation is plastic
