(f). Characteristics of Sedimentary Rocks. Sedimentary rocks can be categorized into three groups based on sediment type. Most sedimentary rocks are formed by the lithification of weathered rock debris that has been physically transported and deposited.Conglomerate is a clastic sedimentary rock made up of rounded clasts that are greater than two millimeters in diameter. The spaces between the clasts are generally filled with sand- and clay-size particles. The rock is bound together by a cement that is usually composed of calcite or quartz.Metamorphic rocks are generally a modified form of Igneous, Sedimentary, or previous Metamorphic rock by various external weather conditions like temperature, pressure, volume, etc. and for such reason, the appearance, texture, and composition of rocks were changed from the previous characteristics.

A wide variety of rocks are formed by different cooling rates and different chemical compositions of the original magma. Obsidian (volcanic glass), granite, basalt, and andesite porphyry are four of the many types of igneous rock. Sedimentary rocks are formed at the surface of the Earth, either in water or on land. They are layered ...Granite. Andrew Alden.
