What is the term for the study of the processes that lead to the preservation of organic remains as fossils?

  1. Paleontology

  2. Taphonomy

  3. Stratigraphy

  4. Sedimentology


Correct Option: B
Explanation:

Taphonomy is the study of the processes that lead to the preservation of organic remains as fossils.

What are the three main stages of taphonomy?

  1. Deposition, Diagenesis, and Lithification

  2. Weathering, Erosion, and Transportation

  3. Burial, Compaction, and Cementation

  4. Permineralization, Carbonization, and Recrystallization


Correct Option: A

What are the two main types of fossil preservation?

  1. Permineralization and Carbonization

  2. Recrystallization and Silicification

  3. Mold and Cast

  4. Trace and Body Fossil


Correct Option: C
Explanation:

The two main types of fossil preservation are mold and cast.

What is a mold fossil?

  1. A negative impression of an organism in sediment

  2. A positive impression of an organism in sediment

  3. A three-dimensional representation of an organism

  4. A trace fossil


Correct Option: A
Explanation:

A mold fossil is a negative impression of an organism in sediment.

What is a cast fossil?

  1. A negative impression of an organism in sediment

  2. A positive impression of an organism in sediment

  3. A three-dimensional representation of an organism

  4. A trace fossil


Correct Option: B
Explanation:

A cast fossil is a positive impression of an organism in sediment.

What is a trace fossil?

  1. A negative impression of an organism in sediment

  2. A positive impression of an organism in sediment

  3. A three-dimensional representation of an organism

  4. A fossil that records the activity of an organism


Correct Option: D
Explanation:

A trace fossil is a fossil that records the activity of an organism.

What is a body fossil?

  1. A negative impression of an organism in sediment

  2. A positive impression of an organism in sediment

  3. A three-dimensional representation of an organism

  4. A fossil that preserves the remains of an organism


Correct Option: D
Explanation:

A body fossil is a fossil that preserves the remains of an organism.

What are the three main factors that affect the preservation of organic remains?

  1. The type of organism

  2. The environment in which the organism lived

  3. The geological processes that occurred after the organism died

  4. All of the above


Correct Option: D
Explanation:

The preservation of organic remains is affected by a combination of factors, including the type of organism, the environment in which the organism lived, and the geological processes that occurred after the organism died.
