Rocks and the Rock Cycle: Metamorphic Rocks

The video explains how powerful forces within the Earth, such as heat, pressure, and chemical reactions, transform rocks into metamorphic rocks. It describes how sedimentary rocks like shale and limestone become slate and marble, respectively, through these processes. Additionally, it covers the transformation of igneous rocks like granite into gneiss.
