WebJul 15, 2024 · There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming … WebSedimentary rocks that are made up of “clasts” are called clastic sedimentary rocks. A comparable term is “detrital sedimentary rocks”. Grain-Size Classification. Geologists that study sediments and sedimentary rocks use the Udden-Wentworth grain-size scale for describing the sizes of the grains in these materials (Table 6.1).
