The video tutorial explains the formation of sedimentary rocks, which involves three main stages: weathering and erosion, sedimentation, and lithification. Weathering breaks down pre-existing rocks into sediments, which are then transported and deposited by natural forces like water and wind. Sedimentation is the accumulation of these sediments at a deposition site. Lithification, also known as consolidation, transforms soft sediments into hard rock through processes like compaction, cementation, and recrystallization. The video concludes with a brief mention of diagenesis, which includes these transformative processes.
