Sedimentary Rocks Is when sediments of rocks, plants, or animals are cemented together, at or near the Earth’s surface.

Sedimentary Rocks Forms through 5 processes: weathering, erosion, deposition, compaction, and cementation.

Weathering Running water or wind breaks rocks or organic material into sediments (pieces of rocks, plants, animals).

Running water or wind carries away sediments. Erosion Running water or wind carries away sediments.

Sediment drops out of water or wind. Deposition Sediment drops out of water or wind.

Pressing of sediment together. Compaction Pressing of sediment together.

Dissolved minerals crystallize and glue sediments together. Cementation Dissolved minerals crystallize and glue sediments together.

Formed when minerals dissolved in a solution crystallize. Chemical Rock Formed when minerals dissolved in a solution crystallize.

Example A – Dolomite

Example B – Limestone (Chemical)

Sediments squeezed together to form a rock. Clastic Rock Sediments squeezed together to form a rock.

Layers in sedimentary rocks Strata (Stripes) Layers in sedimentary rocks

The process called in which sedimentary rocks are arranged in layers. Stratification The process called in which sedimentary rocks are arranged in layers.

Conglomerate rock composed of rounded fragments varying from small pebbles to large boulders in a cement (as of hardened clay)

Breccia a rock composed of sharp or angular fragments embedded in a fine-grained matrix (as sand or clay)

Rock with remains of plants and animals forming layers; fossils Organic Rock Rock with remains of plants and animals forming layers; fossils

Example A – Coal

Example B – Limestone (Organic)
