Reply to comment by Sierra-117- in A recently released set of topography maps provides new evidence for an ancient northern ocean on Mars. The maps offer the strongest case yet that the planet once experienced sea-level rise consistent with an extended warm and wet climate, not the harsh, frozen landscape that exists today. by Wagamaga

I guess it could be a misunderstanding, but what heat the mantle up in the first place? Would those forces not also create a hot core? Does this imply the core was never warm?

If Mars didn’t have a hot core, how could it have produced volcanoes? Or is that also something unknown?
