Rock fragments are small pieces of rock that have broken off from larger formations due to natural processes like weathering and erosion. These fragments can vary in size, from tiny grains of sand to larger chunks, and are often found in soil, riverbeds, and on beaches. They play a crucial role in the formation of sedimentary rocks when they accumulate and compact over time. In geology, rock fragments are important for understanding the history of an area. They can provide insights into the types of rocks present, the processes that shaped the landscape, and even the environmental conditions of the past. Studying these fragments helps scientists learn more about Earth's geological history and ecosystems.
