The correct answer is sedimentary rock. Sedimentary rock is formed from the accumulation of sediment, including organic material such as fossils. Fossils are often found in sedimentary rock layers, which preserve the remains or traces of ancient plants and animals.
The correct answer is sedimentary rock.
To determine which type of rock contains fossils, we need to understand how fossils are formed. Fossils are the remains or traces of ancient organisms that have been preserved in the earth's crust. They form when the remains or traces are buried under layers of sediment and over time, the sediment hardens into rock.
Sedimentary rocks are formed from layers of sediment that accumulate and are compacted over time. These rocks often contain fossils because the layers of sediment can trap and preserve the remains of organisms. Fossils can include the preserved bones, shells, teeth, or imprints of plants or animals that lived long ago.
Metamorphic rocks, on the other hand, are formed when existing rocks are subjected to intense heat and pressure deep within the Earth's crust. This process can alter the structure and composition of the rocks, but it generally does not preserve fossils.
Igneous rocks are formed when molten magma or lava cools and solidifies. Since these rocks are formed from molten material, they generally do not contain fossils either.
So, in summary, sedimentary rock is the type of rock that most commonly contains fossils.
