Here's why:
* Formation: Sedimentary rocks are formed from layers of sediment (like sand, mud, or shells) that accumulate over time. These layers get compressed and cemented together, creating the distinctive flat layers.
* Examples: Common sedimentary rocks include sandstone, limestone, shale, and conglomerate.
While some metamorphic rocks can also exhibit layering, it's typically less distinct than in sedimentary rocks.
