Hi. New to the Civ world, and loving every minute. Here's my newbie question:
Occasionally, I'll see small patches of land marked by another civ's colors, but not connected to their main borders in any way. How does this happen? Is there a way I can somehow "claim" a tile outside of my main borders that I'm missing? Sorry if this has been answered 10 times before, but I didn't notice a previous post about it. Thanks!

Welcome to civfanatics!
I can't be sure, but I expect this to be a case of lack of current information in your game. This game, like many others, has a fog of war system which means that areas outside of the vision range of your units and cities will not be updated with new information like founded cities or expanding culture range of earlier founded cities. When this culture expands into your vision range, then you'll see it, but you won't see the culture area in the fog of war until you move units into that area to update the information or until you exchange maps.
So my guess is that you're seeing a few patches of culture which are in your vision range, but are missing the larger culture area outside of your vision range. So it looks like a few loose patches of culture, but it really is a larger connected culture area.
If this doesn't explain the strange occurrence, then you'll have to upload a screenshot or a save game and I (or someone else) will take a look at it.

It should be noted though that I tend to play on Epic and Marathon speeds (so games progress more slowly, thus there's less to do for more of the early turns and more to do for the later turns), and that I tend to be quite a slow and thoughtful player and thus my turn times probably reside close to the longer end of the spectrum (lots of people probably play faster than me).
