Different Methods of determining the Age of the Stratified Rock Flashcards
In Radiometric dating, the age can be determined by the __________________ of that isotope.
rate of decay
The change in the protein content of a biological sample can be used to determine the age.
Amino acid Dating
Quantitative
Absolute Dating
Exact age
Absolute dating
It is an extended version of the stratigraphy.
Biostratigraphy
Is a technique to determine the numerical age of a rock or a fossil.
Absolute Dating
Absolute dating is also known as __________
Numerical Dating
A particular form of living being may have a ____________________ in their bodies that deteriorates with time.
Protein content
55.7 days half-life
Type I Collagen
High Precision
Absolute dating
Works well with sedimentary
Relative Dating
Qualitative
Relative Dating
The technique used to determine the age by comparing the historical remains to the nearby layers
Relative Dating
In this method, the fossils of one layer are compared with another layer with known dating.
Cross Dating
numerical ages in “millions of years” or some other measurement. These are most obtained via radiometric dating methods performed on appropriate rock types.
Absolute Dating
Expensive
Absolute dating
In geology, determines a chronology or calendar of events in the history of Earth
Dating
In Dendrochronology, what is being measure in a Dicot to know the age of the tree?
Number of Annual Growth RIngs
Low precision
Relative dating
subdivisions of the Earth’s geology in a specific order based upon relative age relationships most commonly in vertical/stratigraphic position. These subdivisions are given names, most of which can be recognized globally, usually on the basis of fossils.
Relative Dating
U238 half-life
4.5 billion yrs
The layers of stratified rocks were formed million years ago. Like fossils and other geological specimens, the age of stratified rocks can be determined using two major geological dating methods called _________ and __________
relative and absolute dating.
This technique assumes that the lowest layer is the oldest while the topmost layer is the youngest layer. It is one of the oldest methods of relative dating.
Stratigraphy
This technique determines the final period during which the object absorbs light, emitting electrons. The age is determined for the emissions.
Thermoluminescence
K40 half-life
1.3 billion yrs.
Order of age of samples
Relative dating
a technique that determines the exact numerical age of a historical remaining.
Absolute Dating
C14 Half Life
5700± 30 yrs
In this technique, the faunal deposits such as fossils of dead animals are used to establish a strategy for dating.
Biostratigraphy
Less expensive and efficient
Relative dating
It determines the age of the sample by measuring the amount of a particular radioactive isotope present in the sample.
Radioactive Dating
Works well with igneous and metamorphic rocks
Absolute Dating
This technique is used to determine the age of the tree.
Dendrochronology
A technique that determines the relative age.
Relative Dating
700 million yrs half-life
UI235
The time needed for one-half of the parent atoms to turn into daughter atoms.
