Is Mars still volcanically active? Is there any evidence that shows or may imply that it is??

posted by Darkmind: “Venus is an odd one. We know that it periodically resurfaces itself every few hundred million years, but we don't know why. It has been argued that the lack of surface water is a factor, as oddly enough water acts as a lubricant in Earth’s plate tectonics. Lack of water combined with active volcanism on Venus might mean that vast pressures build up, leading to periodic resurfacing events. You wouldn't want to live there. At all. [Edited by Don W]
