Grain Sizes of Clastic Sedimentary Rocks

In this minivideo we identify the four size categories for the sediment that will contribute to clastic sedimentary rocks. We use common items as stand-ins for the grain sizes. (Which is sand-sized - ground coffee, orzo pasta, or unpopped popcorn?) Then we show you pictures of clastic sedimentary rocks to see if you can name the rock types. Fun! Take a look, it will make you think differently about quinoa in a very non-hipstery kind of way.
