Question

which correctly lists three materials that preserve soft tissues in fossils?
amber, minerals, and sediment
minerals, permafrost, and amber
permafrost, amber, and tar
sediment, minerals, and tar

Explanation:

• Amber: It can trap organisms (including those with soft tissues) and preserve them over time. For example, small insects have been found well - preserved in amber.
• Permafrost: The extremely cold and stable environment of permafrost can slow down decomposition processes. Woolly mammoths with soft tissues like skin and hair have been found in permafrost regions.
• Tar: Tar pits can act as preservatives. The sticky nature of tar can trap animals, and the anaerobic (oxygen - free) environment within the tar can prevent decay of soft tissues.

Minerals and sediment are more commonly associated with the preservation of hard parts (like bones) through processes such as mineral replacement (in the case of minerals) and burial and compaction (in the case of sediment).

Answer:

permafrost, amber, and tar
