  • Sedimentary Rocks Lesson #13 Volcano World Oregon

    Sedimentary rocks are formed in three ways from these different sized sediments. A sedimentary rock is a layered rock that is formed from the compaction, cementation, and the recrystallization of sediments. Compaction is the squeezing together of layers of sediment due to the great weight of overlying layers of rock.
