Final answer:
Fossils and fossil fuels are primarily found in sedimentary rocks because these rocks form from the compression of sediment, including plant and animal remains, which over time can turn into fossils and fossil fuels.
Step-by-step explanation:
Fossils and fossil fuels are primarily found in sedimentary rocks because these types of rocks provide the most suitable conditions for their preservation and formation. Sedimentary rock is formed from the compression of sediment, which may include things like plant material, shells, and bones. Over millions of years, these materials can be preserved as fossils in the rock. In a similar process, the remains of plants and animals can be transformed into fossil fuels. Sedimentary rocks oftentimes are formed in environments like rivers, lakes, or ocean beds where a lot of organic material can be accumulated, thus increasing the chances of fossil and fossil fuel formation.
