The colors of the earth’s layers show the minerals within the rock. For example, sedimentary rocks with reddish colors have minerals with iron. Iron will combine with oxygen in the air and will produce the mineral hematite or as we more commonly know it, rust. So, colors are the result of the mineralogical content of the layers.
