Pregunta 1
Pregunta
Which burial environment would best promote fossilization
Respuesta
-
burial soon after death by sediments or volcanic ash
-
burial after defleshing of the bones by scavengers and insects
-
burial in groundwater or acidic soils
-
burial in a geologically active area with high ground pressure
Pregunta 2
Pregunta
Relative methods of dating can tell us
Respuesta
-
the approximate numerical age of a fossil
-
the exact numerical age of a fossil
-
whether a fossil is older or younger than another fossil or artifact
-
the amount of organic material remaining in a fossil
Pregunta 3
Pregunta
Radiometric and non-radiometric absolute dating methods both
Respuesta
-
provide only a relative date
-
provide a numerical date
-
measure the radioactive decay of an unstable isotope
-
determine past climate history through stable isotope analysis
Pregunta 4
Pregunta
What must be considered when choosing a radiometric dating method
Respuesta
-
the half-life of an isotope limits its usefulness to a certain date range
-
no radiometric dating methods can date organic materials
-
no radiometric dating methods can date nonorganic materials
-
fossils must be associated with another fossil to give a relative date
Pregunta 5
Pregunta
Stable isotope analysis of carbon in a fossilized tooth would be most useful for determining the
Respuesta
-
relative age of the tooth compared to another fossil
-
absolute age of the tooth
-
temperature of the animal's environment
-
types of plants consumed by the animal during life
Pregunta 6
Pregunta
The molecular clock has been useful to determine the phylogenetic relationships of species based on the assumption that
Respuesta
-
a species lineage accumulates genetic differences over time at a constant rate.
-
only some species are genetically related.
-
DNA is preserved unchanged over long periods of time.
-
species adapt at specific rates.

fluorine dating
Pregunta 8
Pregunta
Paleontologists find a fossil ape with long arms. What type of environment can they infer it inhabited?
Respuesta
-
savanna
-
woodland
-
grassland
-
swamp
Pregunta 9
Pregunta
Studies of temperatures during the Cenozoic era suggest that temperatures have ________ over time.
Respuesta
-
steadily increased
-
steadily decreased
-
fluctuated, sometimes greatly,
-
stayed basically the same
Pregunta 10
Pregunta
The continent that existed about 200 mya, from which the modern continents ultimately emerged, is called
Respuesta
-
Eurasia.
-
Afrinesia.
-
Australasia.
-
Pangaea.
Pregunta 11
Pregunta
A wooden tomb is discovered with a well-preserved mummy inside. Which of the following methods could be used to date the tomb MOST accurately?
Respuesta
-
superposition
-
electron spin resonance
-
thermoluminescence
-
dendrochronology
Pregunta 12
Pregunta
Which era saw the proliferation of mammals?
Respuesta
-
Holocene
-
Cenozoic
-
Jurassic
-
Mesozoic
Pregunta 13
Pregunta
A mummy is discovered whose tomb includes cloth, food, and other organic remains. What dating method would MOST likely be used to date the tomb?
Respuesta
-
biostratigraphy
-
carbon 14
-
dendrochronology
-
electron spin resonance
Pregunta 14
Pregunta
Crucial to creating a fossil record of a species is
Respuesta
-
a living form of the fossil species.
-
a good representation in the fossil record.
-
the preservation of soft tissue such as muscle.
-
the lack of dating; knowing the age of the fossil introduces biases.
Pregunta 15
Pregunta
A hearth is discovered with bone fragments in it. What method might be used to date the bone?
Respuesta
-
dendrochronology
-
electron spin resonance
-
fission track
-
amino acid
Pregunta 16
Pregunta
1. A stratigraphic layer in one location overwhelmingly represents one species, while the same species is discovered in a similar stratigraphic layer hundreds of kilometers away. Biostratigraphic dating method cannot be used to provide an estimate of age for this layer and this species.
Respuesta
- True
- False
Pregunta 17
Pregunta
Temperature estimated using any of several methods is not the most important variable in reconstructing ancient climate
Respuesta
- True
- False
Pregunta 18
Pregunta
Experts reconstruct the appearance of early hominids during life using known relationships between bone and tissue in living animals: layers of clay are built up until finally we can see the ancient face staring at us.
Respuesta
- True
- False
Pregunta 19
Pregunta
Taxonomy is the study of the processes that affect an organism’s remains after death.
Respuesta
- True
- False
Pregunta 20
Pregunta
The three eras that make up Earth history are: Pleistocene, Mesozoic, and Cenozoic
Respuesta
- True
- False
Pregunta 21
Pregunta
Most of the early hominin fossils discovered in Africa come from the eastern and southern parts of the continent because they didn't live anywhere else
Respuesta
- True
- False
Pregunta 22
Pregunta
William Smith was the English surveyor who developed the technique of stratigraphic correlation between regions.
Respuesta
- True
- False
