Assess students' recall of the three major rock types—igneous, sedimentary, and metamorphic—by testing formation processes, key characteristics (texture, grain size, composition), typical examples, and common identifying clues. Items include multiple-choice, short-answer, and matching prompts requiring students to name rock types from descriptions or images and state basic formation environments (cooling of magma/lava; deposition, compaction and cementation; heat and pressure/metamorphism).
