Question

Rocks which contain fossils are ____________
A) Sedimentary rocks
B) Metamorphic rocks
C) Igneous rocks
D) None of these

Answer 1

Hint:
A fossil is any conserved remnants, imprint, or hint of any once-living thing from a past geological age. Examples comprise bones, shells, exoskeletons, and stone marks of animals or microbes, matters conserved in amber, hair, petrified wood, oil, coal, and DNA leftovers.

Complete answer:
Sedimentary rocks are types of rock that are molded by the accretion or sedimentation of mineral or organic elements at the Earth's surface, trailed by cementation. Alluviation is the combined name for procedures that cause these elements to remain on site. The elements that produce a sedimentary rock are called sediment and may be constituted of geological debris or biological debris. The geological debris instigated from surviving and corrosion of prevailing rocks, or from the solidifying of melted lava globules emitted by volcanoes. The geological debris is transferred to the site of accumulation by water, wind, ice, or mass crusade, which are called agents of denudation. Biological debris was created by bodies and parts (mainly shells) of deceased marine creatures, as well as their fecal mass, adjourned in water and gradually stacking up on the base of water bodies (marine snow). Sedimentation may also happen as melted minerals fall from water solution.

Thus, option (A) is correct.

Note:
Provenance is the rebuilding of the source of deposits. All rock uncovered at the Earth's surface is exposed to physical or chemical surviving and broken down into better-grained sediment. All 3 types of rocks (igneous, sedimentary and metamorphic rocks) can be the source of sedimentary debris. Sedimentary provenance lessons resolve to rebuild and understand the history of sediment from the early parent rocks at a source range to final debris at an internment site.
