          • Chapter 1: THE ROCK CYCLE

            Rocks tell the story of the Earth



          • Chapter 2: SEDIMENTARY ROCK AND STRUCTURES: 

            Weathering decomposes bedrocks. Flowing water, wind, gravity, and glaciers then erode the decomposed rocks, transport them downslopes and finally deposit them on the sea coast. Finally, the loose sediment is cemented to form hard sedimentary rock. Sedimentary rocks make up only about 5 percent of the Earth’s crust, but cover about 75 percent of the surface of the continents.

              Depositional environments

              Geologists study sedimentary rocks to help us understand the past. When geologists study sedimentary rocks, they ask questions such as: Where did the sediment originate? Was the sediment transported by a stream, wind, or a glacier? In what environment did the sediment accumulate?. If it was deposited in the sea, was it on a beach or in deep water? If it was deposited on land, was it in a lake, a stream bed, or a flood plain?

              Geologists answer these questions by analyzing the minerals, textures, and structures of sedimentary rocks. Additionally, the size and shape of a sedimentary rock layer contain clues to its depositional environment.Accurate interpretations of depositional environments are often profitable, because valuable concentrations of oil and gas, coal, evaporites, and metals form in certain types of environments. Depositional environments vary greatly in scale, from an entire ocean basin to a 3-meter-long sand bar in a stream. Many small-scale environments may be active within a single large-scale depositional system

          • Chapter 4: Mineralogy

            What is a mineral?

            A naturally occurring substance with a characteristic chemical composition expressed by a chemical formula; may occur as individual crystals or may be disseminated in some other mineral or rock. Most mineralogists include the requirements of inorganic origin and internal crystalline structure. Minerals are the building blocks of the Earth. For example, SiO2 is always the mineral quartz which consists of only two elements. A few elements - carbon, for example - are the only components of minerals. Graphite and diamond are composed only of carbon, each with a different architecture. A rock is a solid material  that is composed of various minerals. Chemical composition and crystalline structure are the two most important properties of a mineral. They distinguish any mineral from all others.
