Here's why:
* Weathering: This is the process where rocks are broken down into smaller pieces by forces like wind, rain, ice, or chemical reactions.
* Erosion: The broken down pieces are then transported by wind, water, or ice.
* Deposition: These pieces eventually settle in a new location, often in layers.
* Compaction and Cementation: Over time, the weight of the layers above presses down on the sediments, compacting them. Minerals dissolved in water act as a cement, binding the particles together. This process forms sedimentary rock.
Examples of sedimentary rocks: sandstone, limestone, shale, conglomerate.
