I just know it is good to hit at the d4 pawn with the >c pawn if possible, but I suspect there is more to it? The other posters have explained perfectly how to eval the position. I'd only add that, as black, I wouldn't like to fight against a strong and well defended knight on e5, which combined with Bb5 pointing to c6, makes black position incomfortable. c5 makes more difficult to support e5 with a pawn, and allow defending c6 with the rook on c8.
