Exploring the Rock Cycle and Types of Rocks

The video explains the rock cycle, detailing how rocks transform between igneous, sedimentary, and metamorphic forms. It describes the processes of weathering, erosion, heat, and pressure that contribute to these transformations. The video also distinguishes between different types of rocks, such as intrusive and extrusive igneous rocks, foliated and nonfoliated metamorphic rocks, and clastic, chemical, and organic sedimentary rocks.
