Sedimentary rocks cover ~ 75% of Earth’s surface. ~ 5 % (by volume) of Earth’s outer 10 miles. Contain evidence of past environments:. Important resource. Coal, oil, and other fossil fuels. Groundwater resources. Did anyone ever have a rock collection?. Where do you think these rocks came from?. Do these rocks last forever?. THE ROCK CYCLE. Earth Science. The Rock Cycle. Rock Cycle – A series of processes that transform material from the stages of magma, igneous rock, sediment, sedimentary rock, or metamorphic rock to another.

A rock is a naturally occurring solid mixture of one or more minerals, or organic matter. Types of Rocks. Sedimentary Rocks. Metamorphic Rocks. Igneous Rocks. Sedimentary Rocks. How They are Made. Wind and water break down the earth. Bits of earth settle in lakes and rivers. Layers are formed and build up. 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. What do rocks look like?. Is this what you thought of?. Or this?. OR THIS????. OR…. THIS!!!!. Rocks can be small or big!. We are going to learn 3 different rocks and how they are made!. Igneous Rock. Color . Texture. Light. Dark. Fine. Coarse . Igneous rocks are classified according to their. . origin. , . texture. , and . mineral composition. .. Origin . D. id it harden inside the earth or on the earth’s surface?. What You Will Learn. Describe the origin of sedimentary rock. . Describe the three main categories of sedimentary rock. . Describe three types of sedimentary structures. . Where does Sand come from?. 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 . . Chemical Sedimentary Rocks. In contrast to detrital rocks, which form from the solid products of weathering, . chemical sediments . derive from ions that are carried in solution to lakes and seas. . 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. BSc 4. th. Semester (Open Elective). Other than Geology main students . Dr. Abdullah Khan . Associate Professor. Department . of Geology, AMU. 1. Clastic. : . Clastic sedimentary rocks are accumulations of clasts: little pieces of broken rock which have been piled up and "lithified" by compaction and cementation.. 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.
