Abstract photography can produce very dramatic images. It relies on our more primal sense of form, color, and curves than it does on detail. The problem is that most photographers tend to think in terms of detail when evaluating photographic opportunities.
Today, matching belts of sedimentary rock, known as the Old Red Sandstone, are found in Scandinavia, the United Kingdom, and eastern North America.

Why do sedimentary rocks sometimes have layers of different colors? Describe the two processes necessary for sediments to lithify into sedimentary rock.
