Sedimentary Rock
- Sedimentary rock is made from sediment and/or by chemical reactions.
- Sediment is loose material, such as bits of rocks, minerals, plants, and animals.
- Water, wind, and ice can move sediment to a place where it settles.
- Whenever this happens a new layer of sediment forms.
- One treasure that can be found in sedimentary rock is fossils.
- Sedimentary rocks are usually formed in oceans and lakes where larger, heavier fragments settle first.
- Limestone is the most abundant chemical sedimentary rock.
- Layers of sedimentary rock are called strata, or beds. These are the most characteristic feature.
- Two different forms of how sedimentary rock is formed are:
1) Compaction
2) Cementation
