Answer Details
Coal and mineral oil are usually found embedded in sedimentary rocks. Sedimentary rocks are formed from the accumulation of sediments such as sand, silt, and clay, which have been compacted and cemented over time. The organic matter of dead plants and animals gets trapped in the sediments during their deposition and gets buried under subsequent layers of sediment. The intense heat and pressure caused by the overlying layers of rock and sediment turn the organic matter into coal or oil. Therefore, coal and mineral oil are usually found in sedimentary rocks.
