What (and how long) would it take for all the water from a Great Flood to go away? How much would such an event shape the geography of the world?
Many worlds have an apocalyptic/cataclysmic event. If mine is a Great Flood, how long would it take for much of the world to be habitable land again? Keep in mind, by the events of the present, the surface of the planet should be ~65% water. The planet is, on average, colder than earth and circa the same size, and civilization doesn't need to recover, camps and villages will suffice. Also, how much would the geography change? And is there a chance of (RELATIVELY) intact artifacts and underwater ruins existing? The civilizations before the floods were quite advanced, so I don't think it's unlikely.
