Formed from clasts (bits and pieces of pre-existing rocks) transported, deposited,and lithified. 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. Sedimentary-sandstone. Metamorphic- gneiss. Igneous- diorite. 1.

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 . 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. . 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 . 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. .
