The Rock Cycle: Summing Up

The video tutorial explains how rocks are formed, the different types of rocks, and the rock cycle. It begins by defining rocks as non-living substances made of minerals. The three main types of rocks—igneous, sedimentary, and metamorphic—are explored, along with their formation processes. The video also covers weathering, which breaks down rocks, and the rock cycle, which describes how rocks transform through melting, weathering, deposition, and metamorphism. The tutorial concludes by encouraging viewers to consider the role of rocks in their daily lives.
