PPT-Sedimentary Rocks Sedimentary Rocks

Sedimentary rocks form in 1 of 3 ways 1 Clastic Sedimentary Rocks made of pieces and grains of other rocks Material such as sand or mud usually deposited in water Conglomerate sandstone. Timing the Geologic Record. . The Stratigraphic Record. Important Principles. Original horizontality—sediments were deposited originally as horizontal beds.. Lateral continuity—beds thin and pinch out laterally.. 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. Chemical Sedimentary Rocks. . Limestone. Chert – Silica. Evaporites. Organic Rocks. Coal. Oil and natural gas. Clastic Sedimentary Rocks. Formed from clasts (bits and pieces of pre-existing rocks) transported, deposited,and lithified. UNIT . 5. 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 .

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. How do chemical sedimentary rocks form?. What are biochemical sedimentary rocks?.

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?. Rocks are classified by how they are formed, their composition, and texture. Rocks change over time through the rock cycle. TYPES OF ROCKS. ROCKS ARE DIVIDED INTO THREE GROUPS BASED ON HOW THE ROCKS . a. metamorphic rock. . b. sedimentary rock. . c. igneous rock. d. sediment. . #1. Which of the following processes is NOT part of the rock cycle?. a. solidification. . b. chiseling. c. erosion. d. metamorphism. 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. . 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. . Clastic. Sediments and Sedimentary Rocks. Clastic sediments are loose materials, however when these sediments under go lithification (. diagenesis. ), they form sedimentary rocks. . Clastic sedimentary rocks are also known as .
