Weathering  – the breakdown of material at the Earth’s surface. g The weathered material is called SEDIMENT.
Sediment  size varies – mud, sand, gravel
Erosion  – movement of sediment from on place to another by WIND, WATER, or ICE.
Deposition  – dropping off the sediment in a new location.
Sediment gets put together into sedimentary rock through  Compaction (Squeezing) Cementation (Gluing)
Sand becomes sandstone
Clay and mud become shale
Gravel becomes conglomerate.
 
Organic sedimentary rock  is formed from previously living things. Limestone – ocean life Coal – plant life on land
