3. Weathering – the breakdown of material at the Earth’s surface. g The weathered material is called SEDIMENT.

4. Sediment size varies – mud, sand, gravel

5. Erosion – movement of sediment from on place to another by WIND, WATER, or ICE.

6. Deposition – dropping off the sediment in a new location.

7. Sediment gets put together into sedimentary rock through Compaction (Squeezing) Cementation (Gluing)

8. Sand becomes sandstone

9. Clay and mud become shale

10. Gravel becomes conglomerate.

12. Organic sedimentary rock is formed from previously living things. Limestone – ocean life Coal – plant life on land

13. Chemical sedimentary rock is formed from water evaporating and leaving rocks behind.

14. Mineral crystals left behind in Death Valley after the water evaporates Playa Lake in California – in the process of evaporating and leaving chemical rock behind
