PPT-Textures and Structures of Sediment and Sedimentary Rocks

Sediment Texture Sediment texture refers to the shape size and threedimensional arrangement of the particles that make up sediment or a sedimentary rock Textures can be clastic or crystalline. . Sedimentary Rocks. What is a sedimentary rock?. Sedimentary rocks are products of mechanical and chemical weathering. They account for about 5% (by volume) of Earth’s outer 10 miles. Contain evidence of past environments. (pages 102–106). 1. Describe how sedimentary rocks form.. 2. List and describe the three major types of sedimentary rocks.. Objectives. write these down!. Sediment. Erosion. Deposition. C. ompaction. Geology 103. Depositional environment. Is the term given to the area where the sediment was originally deposited. Must be inferred from the rock identity. Clastic. . depositional environments. Dominated by actions of waves, tides and currents. Sedimentary rocks 101. Sedimentary rock forms at or near the earth’s surface. Formation.
