When we look at photos of Earth from space, we see a definate terminator. From the ground during Sunset, however, we don't see a wall of dark barrelling for us. I assume this is due to the scattering of light by Earth's atmosphere, which causes the graduation of darkness.
Since the Moon effectively has no atmosphere, is the termintor separation like a wall of light and dark?
