Question

match each type of fossil to its description.
trace fossil
petrified fossil
carbon film
cast
mold
hollow form
detail left after an organism decays
record of an organisms activity
solid copy
living thing turned to rock

Explanation:

• Trace fossil: As the name suggests, it records the activity of an organism, such as footprints, burrows, etc.
• Petrified fossil: Occurs when a living thing is replaced by minerals and turned to rock through a process called permineralization.
• Carbon film: Forms when an organism decays, leaving behind a thin film of carbon that preserves some details of the organism.
• Cast: Is a solid copy of an organism's shape. It forms when minerals fill in a mold (an impression of an organism).
• Mold: Is a hollow form. It is an impression of an organism left in sediment or rock.

Answer:

• trace fossil: record of an organism’s activity
• petrified fossil: living thing turned to rock
• carbon film: detail left after an organism decays
• cast: solid copy
• mold: hollow form
