sedimentary rock facts for kids - EAS
- Sedimentary rocks are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans.
- This sediment can include minerals, small pieces of plants and other organic matter.
- The sediment is compressed over a long period of time before consolidating into solid layers of rock.
- Sedimentary rocks forms layers called strata which can often be seen in exposed cliffs.
- Sedimentary rocks cover the majority of the Earth's rocky surface but only make up a small percentage of the Earth’s crust compared to metamorphic and igneous types of rocks.
- Examples of sedimentary rocks include limestone, sandstone, mudstone, greywacke, chalk, coal, claystone and flint.
