Exploring the Formation Process of Clastic Sedimentary Rocks

This video tutorial explains the formation of clastic sedimentary rocks, the most common type of sedimentary rocks on Earth's surface. It covers the three main steps: weathering, transportation, and lithification. Weathering breaks down preexisting rocks into sediments, which are then transported by agents like rivers, winds, and glaciers. Finally, sediments are deposited, compacted, and cemented to form new rocks such as shale, sandstone, and conglomerate.
