Lets say there is a gas giant similar to Jupiter orbiting a yellow star similar to our Sun. The planet and moon orbit at a distance that would resemble in between Mars and Earth. So the moon would receive 70% the sunlight that Earth receives. Around this planet exists a moon with 0.064 Earth masses and 0.4 Earth radii. This would put it into the rocky moon category. The moon orbits at Europa's distance from the planet with a slightly eccentric orbit and the interior would be pushed and pulled by interactions with other moons. Could the tidal heating from the planet cause geological activity on the moon and create an atmosphere in the process? If so how thick could the atmosphere become?
