Question

Why is it most likely that fossils will be found in sedimentary rock rather than igneous or metamorphic rock?

A. Molten sedimentary rock burns up living organisms and fossilizes them as it cools.
B. Animals can dig into sedimentary rock, and some are trapped inside and fossilize.
C. Sedimentary rock breaks apart most easily, so fossils inside are seen more often.
D. Organisms can get trapped and fossilize as the layers of sedimentary rock form.

Answer 1

Fossils are most likely to be found in sedimentary rock because sedimentary rock forms from the accumulation of sediments that can quickly cover and preserve the remains of organisms. Igneous and metamorphic rock, which form from processes involving heat and pressure, typically destroy fossils.

Step-by-step explanation:

Fossils are most likely to be found in sedimentary rock rather than igneous or metamorphic rock because of the conditions that are required for fossil formation. Sedimentary rock forms from the accumulation of sediments, such as sand, silt, and clay, which can quickly cover and preserve the remains of organisms. As new layers of sediment are deposited, the pressure and time can lead to the formation of sedimentary rock.

Organisms can become trapped and fossilized within these layers over time. In contrast, igneous and metamorphic rock form from processes involving heat and pressure, which typically destroy any fossils that may have been present.
