Sedimentary rocks are formed through the accumulation and compaction of mineral and organic particles over time. They often develop in layers, with each layer representing a different period of deposition. Common examples include sandstone, limestone, and shale, which can provide valuable information about Earth's history and past environments. These rocks are typically found in areas where water, wind, or ice has transported sediments. Sedimentary rocks play a crucial role in the carbon cycle and can also contain important resources such as fossil fuels and groundwater. Their study helps geologists understand the processes that shape our planet.
