Clastic | Rock that formed from the fragments or pieces of other rocks and can be identified by size |
Crystalline | Rock that formed from mineral grains that fall out of the solution by evaporation |
Bioclastic | rock that formed from the remains of plants and animals |
Formation | How the clasts of a sedimentary rock are held together |
Cementation | Often clasts such as clays, sands, and silts are glued together |
Compaction | A reduction in volume of sedimentary layers due to increasing weight of overlying |
Chemical Action | A rock formed when dissolved minerals in water form a crystalline mass of ingrown mineral crystals after evaporating |
Characteristics | The properties and traits that may help identify a sedimentary rock |
