GEOLOGY

Detailed explanation-1: -Fossils are commonly found in sedimentary rocks. Sedimentary rocks are the most common type of rock since they are formed by the earth’s natural forces like wind and water. Q. Sometimes igneous and sedimentary rocks are changed into metamorphic rocks.

Detailed explanation-2: -Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.

Detailed explanation-3: -Most fossils “hide out” in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils. Two examples of sedimentary rocks are sandstone and shale.

Detailed explanation-4: -Sedimentary rocks have the ability to retain fossils because unlike most igneous and metamorphic rocks, sedimentary rocks occurs at temperatures and pressure that do not obliterate fossil remnants. Therefore, fossils are found in sedimentary rocks.

Detailed explanation-5: -Since rapid burial in sediment is important for the formation of fossils, most fossils form in marine environments, where sediments are more likely to accumulate. Fossils come in many types.
