The Rock Cycle

Readers explore The Rock Cycle, learning how rocks constantly change from one type to another. The book introduces the three main rock families igneous, sedimentary, and metamorphic and explains how each forms from molten magma, deposited sediments, or heat and pressure. With diagrams and examples, it follows the journey of rocks as they melt, erode, compact, and recrystallize over millions of years. This overview gives middle-grade students a solid foundation in geology and the dynamic processes that constantly reshape our planet.
