GEOLOGY

Detailed explanation-1: -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-2: -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-3: -Igneous and metamorphic rocks experiences too much changes in temperature and pressure, due to which fossils can not be preserved in these rocks. The pressure and temperature in sedimentary rocks is quite less, that helps in the preservation of fossil fuels. Therefore, fossils are found only in sedimentary rocks.
