1 Chapter 6, Section 3 Sedimentary Rock Sedimentary RockForms from the cementing and compaction of layers of sediment Sediment is leftover pieces of other rocks, like sand, clay, pebbles and silt

2 3 types of sedimentary rock Clastic Chemical Organic

3 ClasticFormed from fragments of other rock Sediments on a river get sorted out and then bind/stick together

4 Sorting of sediments

5 Silt forms…. Sands form…. Pebbles and gravels and sands form… Shale Sandstone Conglomerate

6 Compaction Cementation The pressing together of a rock’s materials The natural “glue” that holds rocks together

7 Chemical RockForms from dissolved minerals Minerals precipitate out of water Halite

8 Salt Flat

9 Organic RockFrom from the remains of plants and animals Coal Organic Limestone

10

11 Features of sedimentary Rock Stratification Fossils Ripple Marks Mud Cracks Geodes

12 StratificationLayering

13 FossilsRemains of a plant or animal left in a rock

14 Ripple marksLeft by water

15 Mud cracksLeft by the lack of water

16 GeodesFine quartz crystals lining the inside of a limestone rock
