1 Sedimentary Rock 12/4/ pgs IN: Describe how igneous rock is classified. Put your DRW on the box

2 I GNEOUS R OCK - T EXTURE AND COMPOSITION Texture – where the magma cools Intrusive – coarse grained Extrusive – fine grained

3 I GNEOUS R OCK - T EXTURE AND COMPOSITION Composition – color Felsic – light colored less dense Mafic – dark colored more dense

4 H OW DOES SEDIMENTARY ROCK FORM ? 1. Weathering and erosion creates sediment followed by, 2. compaction and cementation forms sedimentary rock.

5

6 W EATHERING Wind, water, ice, sunlight, and gravity all cause rock to weather into fragments. These small fragments are called sediment.

7 E ROSION Sediments are transported from one place to another. rivers

8 C OMPACTION The layers eventually become compacted.

9 C EMENTATION Dissolved minerals separate out of the water to form a natural glue that binds the sediments together.

10 Strata - the layers of sedimentary rock that form from the deposition of sediment.

11

12 S EDIMENTARY ROCK Form at or near the Earth’s surface. Their physical features tell part of Earth’s history.

13 S TRATA Sometimes records the motion of wind and water waves.

14 C OMPOSITION 1. Clastic 2. Chemical 3. Organic

15 C LASTIC SEDIMENTARY ROCK Forms when rock or mineral fragments, called clasts, stick together. sandstone Names of clastic sedimentary rock are based on grain size.

16 C HEMICAL SEDIMENTARY ROCK Forms when minerals crystallize out of a solution, such as sea water, to become rock. limestone

17 O RGANIC SEDIMENTARY ROCK Forms from the remains of organisms. fossiliferous limestone

18 T EXTURE Stratification - the layering of rock. Strata differ from one another depending on the kind, size, and color of their sediment.

19 C ONGLOMERATE Sedimentary rock that resembles concrete. Clastic Coarse-grained

20 S ANDSTONE Sedimentary rock formed from sand. Clastic Coarse-grained

21 S HALE Sedimentary rock also known as mudstone. Clastic Fine-grained

22 F OSSILIFEROUS L IMESTONE Sedimentary rock made from shells and coral. Organic

23 C OAL Sedimentary rock made from fossilized carbon Organic

24 OUT: Describe the process by which clastic sedimentary rock forms.
