-Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.
Explanation:
-Sedimentary rock, also called stratified rock, is formed over time by wind, rain and glacial formations. These rocks may be formed by erosion, compression or dissolution. Sedimentary rock may range from green to gray, or red to brown, depending on iron content and is usually softer than igneous rock.
