Multiple Choice

Which of the following statements is true about the role of organic compounds in the formation of fossils?

Organic compounds in fossils are completely replaced by inorganic minerals during fossilization.

Organic compounds are preserved in fossils due to rapid burial and mineralization.

Fossils contain organic compounds that remain unchanged over millions of years.

Fossils are formed only from inorganic materials, excluding any organic compounds.

Verified step by step guidance

Understand the process of fossilization: Fossilization is a complex process that involves the preservation of organic material through rapid burial and mineralization.

Consider the role of organic compounds: Organic compounds can be preserved in fossils if the conditions are right, such as rapid burial which limits decay and allows for mineralization.

Evaluate the statement about complete replacement: While some organic material may be replaced by minerals, it is not always completely replaced. Some organic compounds can remain preserved.

Analyze the statement about unchanged organic compounds: Over millions of years, organic compounds can undergo changes, but some may remain relatively intact depending on the conditions.

Conclude with the correct statement: The statement that organic compounds are preserved in fossils due to rapid burial and mineralization is true, as it aligns with the known processes of fossilization.
