Lines don't exist in nature. So why is it that we see lines everywhere we look? Well, lines are a shortcut that our minds use so we don't have to process all that other information.

In these three rocks we can see lines, or bands of contrasting material in the rock. These stripes of white running all the way around the outside of each rock are actually narrow layers of quartz sandwiched inside the rock mass. The wider the line, the thicker the layer of quartz. The banding looks different on each rock because the part we see follows the outside contours of that rock. We don't see the rest of the quartz layer that's on the inside of the rock.
