Question
Which type of rocks is most likely to contain
fossils?Solution
Sedimentary rocks are formed from the accumulation and cementation of mineral and organic particles over time. They are the most common type of rocks where fossils can be found because they form in layers at Earth's surface where organisms are buried and preserved quickly after death. Fossils represent past life forms, and their presence in sedimentary rocks provides important insights into Earth's biological and geological history.
