Formation Sedimentary rocks are classified based on formation Sedimentary rocks form at or near the surface, OFTEN NEAR BODIES OF WATER

Weathering Breaking down of rock into sediments by wind, water, ice, sunlight, & gravity

Erosion Movement of sediment(transport to another place)

Sediment Rock & mineral fragments(weathered rock pieces)

Deposited Sediment deposited(dropped to rest) in layers called strata

Compacted Pushed together

Cemented Dissolved minerals such as quartz or calcite act as a natural glue cementing sediment together to form the rock

Strata Layers found in sedimentary rock(youngest rocks on top, oldest rock on bottom=superposition)

Clastic(pieces sticking out) Rock & mineral fragments compacted & cemented together Classified by grain size Ex. Sandstone, breccia, conglomerate, shale

Chemical(dissolve and crystallize) Formed from solutions of dissolved minerals & water Minerals crystallize out of solution Ex. Halite, limestone, gypsum

Organic(from once living=fossils) Contain remains, fossils of ocean animals Ex. Fossiliferous limestone Ex. Coal- forms underground from plant material buried under sediment & changed to coal over millions of years
