The Rock Cycle Explained: Metamorphic, Igneous, and Sedimentary Rocks #3809172 (License: Personal Use)

This educational diagram illustrates the dynamic rock cycle, highlighting key processes such as melting, cooling, heat and pressure, weathering, lithification, and compaction. It shows how metamorphic rocks form from pre-existing rocks under intense heat and pressure, and how all rock types can transition into one another. The top section features detailed sketches of common metamorphic rocks like gneiss and schist.

Used in earth science classrooms, geology websites, and educational resources to teach students and learners about rock classification and geological processes; matches user intent for academic study or curiosity about Earth’s materials.
