Unscramble the Blue Letters

That means that for each meter of a cave that we already know, that we have explored, there are still some tens of kilometers of undiscovered passages. That means that this is really an elnesds continent, and we will never be able to explore it completely. And this estimation is made without considering other teyps of caves, like, for example, inside galirecs or even volcanic caves, which are not karstic, but are formed by lava folws. And if we have a look at other planets like, for example, Mars, you will see that this characteristic is not so specific of our home planet. However, I will show to you now that we do not need to go to Mars to explore aeiln worlds.
