Discover the wonders of our earth with the Physical Geography DVD Series. This DVD covers sedimentary rocks, and teaches students about sandstone, limestone, siltstones, coquina, mudstones, shale, dolomites, conglomerates, fossil limestone and sandstones. This program investigates how weathering breaks up rock and the this sediment is later turned into the various kinds of clastic and non-clastic rocks. The program also shows how students can make sedimentary rock using simple, everyday materials. Subjects covered include: how sedimentary rocks are classified; how earth materials are carried by wind, water and ocean currents; how to distinguish between clastic and non-clastic sedimentary rocks; how cementing agents keep individual rocks together; how running water carries its load of rock particles; how geologists use sedimentary rock to study ancient life; and a look at evaporates such as salt and gypsum deposits.
