Most fossils are found in sedimentary rock D. Sediments are cemented together by dissolved minerals (sand becomes sandstone) E. Geologic time scale was worked out by observing sedimentary rock layers and fossils F. Common sedimentary rocks clay (tiny particles) shale (from fine mud particles) sandstone (sand) conglomerate (gravel) coquina (seashells) limestone (precipitates or tiny skeletons) Metamorphic rocks A. rocks that have been changed by heat and pressure B. heat and pressure cause minerals to move around and change, producing banding C. pressure can cause bending and folding D. can also can cause cracking and faulting D. examples: marble from limestone quartzite from sandstone slate, phyllite, schist, and gneiss from shale Rock Cycle A. Rocks are recycled over many millions of years B. Rocks are weathered and particles are transported, deposited, and cemented into sedimentary rocks C. Rocks are pushed deep into the crust where they are melted, become new igneous rocks when cooled D. Rocks are subjected to enough heat and pressure for some of their minerals to migrate, producing metamorphic rocks
