Chemical sedimentary rocks form when dissolved materials preciptate from solution. In this video, you’ll learn how each type of rock forms, how to identify a rock’s type and how the processes of the rock cycle can move sediment and change one type of rock into another. Conglomerate fragments are commonly deposited along the shoreline or stream channel and they are pea-sized or larger. So what kind of rock do you have in your collections. Crystal size is determined by how slowly the magma cools. Earthquakes and the Earth's internal structure. Chemical sedimentary rocks such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Igneous Rocks.

Rocks that are the result of the processes of weathering and erosion which are continually breaking down and rearranging them. If you see this, then you know that there’s been some kind of major geological movement that moved that layer of rock after it was formed. Sedimentary rock- formed when material from the Earth’s crust is deposited and hardens in water (limestone, coal, shale). Scuba divers who have seen mud and shells settling on the floors of lagoons find it easy to understand how sedimentary rocks form. A few examples include obsidian and pumice. Over a period of time, sediment is cemented together to form sedimentary rocks. Compacted and dried mud flats harden into shale. They consist mainly of plagioclase minerals that are mixed together with hornblende, biotite and pyroxene.
