Hint: Any preserved remains, impression, or residue of any once-living thing from a previous geological age is referred to as a fossil. Examples include bones, shells, animal or microbe imprints in stone, amber-preserved artefacts, fur, petrified wood, oil, coal, and DNA residues. The compilation of all fossils is known as the fossil record.
Complete answer:
The majority of fossils are found in sedimentary rocks, where gentler pressure and lower temperatures enable past life-forms to be preserved. As sediments such as mud, sand, shells, and pebbles cover plant and animal species and retain their characteristics over time, fossils are formed.
Now. Let us look at the given options:
A) true: This option is incorrect because Fossil fuels are rarely found in metamorphic and igneous rocks. Sedimentary rocks are where they are most commonly found.
B) false: This is the correct option. Fossils are most often found in sedimentary rock, which is one of the three main types of rock. Sedimentary rocks, unlike most igneous and metamorphic rocks, form at temperatures and pressures that do not kill fossil remains. These fossils are frequently only apparent under magnification.
Thus, the correct answer is Option B. False.
Note: Sedimentary rocks are formed by the deposition or aggregation of mineral or organic particles at the Earth's surface, followed by cementation. The processes that allow these particles to settle in place are referred to as sedimentation. Sediment is the term for the particles that make up a sedimentary rock.
