Unformatted text preview: sturdy earth. For instance, some species of animals will eat rocks (geophagy) as a way to aid in digestion. These rocks eventually leave the system, and are pocketed back into the earth’s cycle. Plants use the earth as a way to ground themselves, and often, these plants and animals are fossilized within the earth’s sedimentary layers. Fossilization takes time, however, and many are left chipped and fragmented from other earth processes. This lab detailed three things: how to determine rock “species”, defining properties of rocks, and classifying rocks. It was also indicated common markers for certain types of rocks, such as “dense, hard, glassy” being of igneous rock type. Or, “folded texture” for metamorphic rocks. This lab experience also highlighted the necessity of deeper, more inclusive geologic factors, looking beyond the Moh’s hardness scale and color....
