2Relative methods of dating can tell us
- Athe approximate numerical age of a fossil
- Bthe exact numerical age of a fossil

- Dthe amount of organic material remaining in a fossil
3Radiometric and non-radiometric absolute dating methods both

- Bprovide a numerical date
- Cmeasure the radioactive decay of an unstable isotope
- Ddetermine past climate history through stable isotope analysis
4What must be considered when choosing a radiometric dating method
- Athe half-life of an isotope limits its usefulness to a certain date range
- Bno radiometric dating methods can date organic materials
- Cno radiometric dating methods can date nonorganic materials
- Dfossils must be associated with another fossil to give a relative date
5Stable isotope analysis of carbon in a fossilized tooth would be most useful for determining the
- Arelative age of the tooth compared to another fossil
- Babsolute age of the tooth
- Ctemperature of the animal's environment
- Dtypes of plants consumed by the animal during life
6The molecular clock has been useful to determine the phylogenetic relationships of species based on the assumption that
- Aa species lineage accumulates genetic differences over time at a constant rate.
- Bonly some species are genetically related.
- CDNA is preserved unchanged over long periods of time.
- Dspecies adapt at specific rates.
7Igneous rock can be dated with which of the following methods?
- Aradiopotassium dating
- Bdendrochronology
- Cradiocarbon dating
- Dfluorine dating
8Paleontologists find a fossil ape with long arms. What type of environment can they infer it inhabited?
- Asavanna
- Bwoodland
- Cgrassland
- Dswamp
9Studies of temperatures during the Cenozoic era suggest that temperatures have ________ over time.
- Asteadily increased
- Bsteadily decreased
- Cfluctuated, sometimes greatly,
- Dstayed basically the same
10The continent that existed about 200 mya, from which the modern continents ultimately emerged, is called
- AEurasia.
- BAfrinesia.
- CAustralasia.
- DPangaea.
11A wooden tomb is discovered with a well-preserved mummy inside. Which of the following methods could be used to date the tomb MOST accurately?
- Asuperposition
- Belectron spin resonance
- Cthermoluminescence
- Ddendrochronology
12Which era saw the proliferation of mammals?
- AHolocene
- BCenozoic
- CJurassic
- DMesozoic
13A mummy is discovered whose tomb includes cloth, food, and other organic remains. What dating method would MOST likely be used to date the tomb?
- Abiostratigraphy
- Bcarbon 14
- Cdendrochronology
- Delectron spin resonance
14Crucial to creating a fossil record of a species is
- Aa living form of the fossil species.
- Ba good representation in the fossil record.
- Cthe preservation of soft tissue such as muscle.
- Dthe lack of dating; knowing the age of the fossil introduces biases.
15A hearth is discovered with bone fragments in it. What method might be used to date the bone?
- Adendrochronology
- Belectron spin resonance
- Cfission track
- Damino acid
