Analyzing and Interpreting the Shape of Sand Particles
The size, shape, and roundness help to explain the sandstone’s "life history." This lab emphasizes two points. First, sand composition reflects the sand’s source. Second, the roundness of individual sand particles reflects how far the sand traveled and for how long. Sand is usually created when water and/or wind break off small pieces of pre-existing rock.
