Is it possible for a geologically active 'rogue planet' to support life?

+0
−0

After reading a couple dozen entries about rogue planets and their implications (for those unaware, a rogue planet is a planetary mass that has been separated from the star by gravitational instability or otherwise forceful means).

If a planet was geologically active underneath the surface, enough so that the surface of the planet was heated above freezing temperature, would it be viable for life to evolve on the planet? The planet would, obviously, be bombarded periodically by meteorites of various sizes, and the surface must be exceedingly cold. But, as theorized with a few moons in our Solar System, wouldn't underlying water be able to be heated to the point where life is possible?
