Lets say mars has a density of 6 g cm/3 instead of its current density and kept its radius. What would the effects of this increased mass be? Im curious on the interior like the core and mantle. Im curious about the surface like mountain height, rate at lava flow, geologic activity. Also am curious about the icreased effects on the atmosphere and what it would mean for the jetstream flow and air pressure and if it would be enough to heat the core to a molten state. Thank you for your time.
