Document Summary
Minerals are the building blocks of rocks that are defined as being: naturally occurring inorganic solids with a well defined structure and composition. Rocks are well-consolidated aggregates of one or more minerals. Sedimentary rocks (two types) are rocks produced by the lithification of clastic and chemical sediment. They form sediment break down of weathered rock glued together again that"s a sedimentary rock. Sediment loose fragments (grains) produced by the breakdown (weathering) of rocks or by the precipitation of chemical processes: Precipitation and settling of particles from a fluid. Sedimentary rock rocks produced by the lithification of clastic, biochemical, organic and chemical sediment. Step 1 weathering break down preexisting material. Step 2 transportation take material and move it from original source. Step 3 deposition accumulate the material somewhere. Step 4 lithification gluing that sediment together dry out water to cement it together. Sedimentary rocks can b divided into two broad groups:
