What type of rock includes examples such as limestone, conglomerate, dolomite, and shale?

Sedimentary rocks are formed through the accumulation and compaction of mineral and organic particles, as well as the precipitation of minerals from solution. Limestone, conglomerate, dolomite, and shale are all prime examples of sedimentary rocks, each formed from different processes.

Limestone primarily consists of calcium carbonate and often forms from biological processes, such as the accumulation of shells and coral. Conglomerate is made up of rounded fragments cemented together, indicating that it has been formed from larger particles transported by water. Dolomite can result from the alteration of limestone and contains magnesium carbonate, and shale is formed from fine-grained mud and clay particles, exhibiting layered structures.

These rocks are significant in understanding Earth's history, as they often preserve fossils and provide insights into past environments. Identifying them correctly as sedimentary rocks is essential for geological classification and studying processes like erosion, sedimentation, and the rock cycle.
