Weathering of ________ Calcium Carbonate _______ Have you ever tried to build a sand castle at the beach? Did you ever wonder where the sand came from? Weathering of ________ Calcium Carbonate _______ Both are Compacted together and compressed to form Sandstone

Origins of Sedimentary Rock 1) __________ from: wind, water, ice, sunlight, and gravity = small fragments 2) _________ moves sediment from one place to another

3) ___________ is the process by which sediment settles out of the water or wind carrying it. •Different types of sediment are ____, bones, _____, stems, and other ________ of living things.

4) As new layers of sediment occur, they _________ the older layers. 5) Quartz and Calcite let water seep (or evaporate) past them to form a natural _________. Occurs over millions of years. • Transforms loose sediments into solid sedimentary rock

Locations of Sedimentary Rock Near the Earth’s surface = no internal heat or pressure from the core Visual cues= _______ __________(STRATIFICATION)

Sandstone –So… How do we go from sediment to Sedimentary rock??? –You tell me! 1.Weathering Sediment 2.Erosion 3.Deposition occurs 4.Compaction occurs 5.Cementation occurs Sandstone

Composition: Sedimentary Rock is Classified by how it forms Clastic: Minerals (clasts) cement together _________________ Chemical: Crystalize from a solution like seawater ________________ Organic: Remains of plants & animals _____________

1) Clastic Rocks A sedimentary rock that forms when rock fragments are ___________ together The fragments range in size Grouped by the _________ of rock fragments or particles in which they are made. –Shale •Forms from tiny particles of clay. •_____________ is needed to hold the clay particles together.

______________ Forms from the sand on beaches, on the ocean floor, in riverbeds, and in sand dunes.

Conglomerate rocks have fragments with _________ edges. Breccia rocks are make up of large fragments with __________ edges.

2) ORGANIC Sedimentary Rocks –Form where the remains of plants and animals are _________ in thick layers –Two important organic rocks are ___________________. –Coal –forms from the remains of swamp plants buried in water.

Limestone –the _____________ of living things Limestone forms from the _______ found in the shells and skeletons of coral, clams, oysters, and snails.

Another example of limestone is ________. (sediments of the skeletons of microscopic living things found in the oceans.)

3) Chemical Rocks -form when minerals that are dissolved in a solution, __________________. ____________ can form when calcite that is dissolved in lakes, seas, or underground water comes out of solution and forms crystals. Chemical Rocks

What are some Sedimentary Rock Uses… Chemical sedimentary rocks also form when mineral deposits are left when seas or lakes __________ –rock salt is made of the mineral __________. Large deposits of rocks formed by evaporation are found only in dry climates What are some Sedimentary Rock Uses…
