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. 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?. 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 . 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. NAME THAT ROCK!. This rock is formed by cooling Magma. Igneous. This is formed underwater. It is made up of bits of shells and skeletons of sea animals. Sedimentary . This rock is formed by limestone that has been exposed to heat pressure.. . 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. SEDIMENTARY ROCKS. Geo 281: geology for engineers. Geology and Geophysics Department. King Saud University. What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand . 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.
