Sedimentary Rocks and Processes

The video introduces sedimentary rocks, explaining their formation from sediments that settle in layers over time. It describes how these sediments, composed of eroded rock particles and organic material, compress to form rocks like limestone, chalk, sandstone, and coal. The video also promotes the MakeMeGenius website for more educational resources.
