Sedimentary Rocks and Processes

The video tutorial explains sedimentary rocks, focusing on limestone, sandstone, and shale. It covers their formation, characteristics, and the processes of compaction and cementation. The video also discusses the role of erosion and weathering in shaping rock formations and the significance of fossil layers in understanding geological history. Safety guidelines for experiments and additional resources are provided.
