Classifying Rocks: Igneous, Sedimentary, and Metamorphic

Help students become rock stars with this informative geology worksheet! Learners will begin by reading about the three main types of rocks: igneous, sedimentary, and metamorphic. Young geologists are then presented with five different mystery rocks. By reading about the formation and appearance of each rock, students will determine which of the three main rock types it is.

This worksheet will get third and fourth graders to think critically about how and where different rocks are formed. Understanding the three main types of rock and how they form provides foundational knowledge as learners continue to study earth science.
