Frage 2
Frage
Relative methods of dating can tell us
Antworten
-
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
Frage 3
Frage
Radiometric and non-radiometric absolute dating methods both
Antworten
-
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
Frage 4
Frage
What must be considered when choosing a radiometric dating method
Antworten
-
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

Frage 11
Frage

Antworten
-
superposition
-
electron spin resonance
-
thermoluminescence
-
dendrochronology
Frage 12
Frage
Which era saw the proliferation of mammals?
Antworten
-
Holocene
-
Cenozoic
-
Jurassic
-
Mesozoic
Frage 13
Frage
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?
Antworten
-
biostratigraphy
-
carbon 14
-
dendrochronology
-
electron spin resonance
Frage 14
Frage
Crucial to creating a fossil record of a species is
Antworten
-
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.

Antworten
-
dendrochronology
-
electron spin resonance
-
fission track
-
amino acid
Frage 16
Frage

Antworten
- True
- False
Frage 17
Frage
Temperature estimated using any of several methods is not the most important variable in reconstructing ancient climate
Antworten
- True
- False
Frage 18
Frage
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.
