Rock Type Identification

This worksheet provides twelve rock descriptions from a “Rock Museum Exhibit,” and students must identify each as igneous, sedimentary, or metamorphic. Learners read clues about how each rock forms-such as cooling speed, compaction, pressure, or heat-and then classify it correctly using the letters I, S, or M. This strengthens students’ ability to distinguish between rock types based on formation processes and physical characteristics. The exercise promotes close reading, scientific vocabulary application, and classification skills. Students deepen their understanding of how environmental conditions shape texture, crystal size, and layering. This worksheet supports foundational Earth science knowledge necessary for advanced study.
