Description

A rock formed by the accumulation and consolidation of small grains of mineral matter. Sedimentary rocks usually have strata formed by deposition variations. Each layer can contain a mixture of mineral particles eroded from different sources. The particles are often rounded due to wear and abrasion. Examples of sedimentary rocks are Shale, Sandstone, Siltstone, and Limestone.
