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: -Metamorphic rock, such as marble, is formed by tremendous heat and pressure. Fossils are not usually found in either igneous or metamorphic rocks.

Detailed explanation-3: -Metamorphic rocks such as marble are formed by tremendous heat and pressure and fossils can not be found in such places. They are usually found in Sedimentary rocks as these rocks have formed at low temperatures and pressure and suitable for fossils.

Detailed explanation-4: -Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

Detailed explanation-5: -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.
