What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand . which are . transported by the action of water, wind, glacial ice and . gravity.. These . materials are . What is the difference between clastic and non-clastic sedimentary rocks? . What we know. The process of formation for a sedimentary rock involves the following steps:. Weathering. Erosion. Deposition. Favs. .. . Where do sediments come from?. - Weathering. – breaking down rock into smaller pieces chemically and physically.. - Erosion. - carrying away the particles and depositing them. . Glaciers. What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand . which are . transported by the action of water, wind, glacial ice and . gravity.. These . materials are . Sedimentary structures. Sedimentary structures.  are those structures formed during sediment deposition. .. Sedimentary structures such as . cross bedding, graded bedding, mud . cracks, . Strata. A rock is a natural substance that is made up of solid crystals of different minerals that have been fused together into a solid lump. . Rocks can be classified by their attributes: . Texture. Hardness. Sediment . Texture. Sediment texture refers to the shape, size and three-dimensional arrangement of the particles . that make . up sediment or a sedimentary rock.. Textures can be . clastic or . crystalline. Do Now. 1.  What is an igneous rock?. 2. How do sedimentary rocks form?. Sedimentary Rocks -. are one of the three main rock types . A sedimentary rock can form one of three ways: . by the . deposition.
