Does the surface of the moon look like we would expect if it was once molten??
If the moon was molten at one time, the magma would have undergone a daily tide cycle due to the gravitational pull of the earth. The tidal shifts would have been massive, especially presuming that the moon was closer to the earth at that time. As the moon hardened, wouldn't the surface have been textured by the rising and falling tidal magma as it slowly cooled? You would get a wave like swirled pattern similar to what you would get if you let a bucket of plaster harden while you were tipping the bucket back and forth. Wouldn't that pattern still be very visible since the moon hasn't really changed much since it's formation? Wouldn't the surface look a little more like the grooves and ridges seen on Jupiter's Ganymede?
