Exploring the Formation of Sedimentary Rocks

The video tutorial explains how sedimentary rocks are formed through a series of processes: weathering, erosion, deposition, compaction, and cementation. Weathering breaks down rocks into smaller pieces, while erosion transports these sediments to new locations. Deposition occurs when sediments settle in a new place, and compaction compresses them over millions of years. Cementation bonds the sediments into new rocks. The video also discusses how sedimentary rocks can be exposed and reveal fossils. A review of these processes concludes the tutorial.
