The oldest dating method which studies the successive placement of
layers. It is based on the concept that the lowest layer is the oldest and the topmost
layer is the youngest.
Stratigraphy
Biostratigraphy
Cross Dating
Fluorine Dating
This method compares the age of remains or fossils found in a layer
with the ones found in other layers. The comparison helps establish the relative age
of these remains.
Stratigraphy
Biostratigraphy
Cross Dating
Fluorine Dating
An extended version of stratigraphy where the faunal deposits
are used to establish dating. Faunal deposits include remains and fossils of dead
animals.
Fluorine Dating
Cross Dating
Biostratigraphy
Stratigraphy
Bones from fossils absorb fluorine from the groundwater. The
amount of fluorine absorbed indicates how long the fossil has been buried in the
sediments.
Fluorine Dating
Cross Dating
Biostratigraphy
Stratigraphy
It determines the period during which certain object was last
subjected to heat. It is based on the concept that heated objects absorb light and
emit electrons. The emissions are measured to compute the age.
Amino acid dating
Dendrochronology
Radiometric dating
Thermoluminescence
Each tree has growth rings in its trunk. This technique dates
the time or period during which these rings were formed.
Amino acid dating
Dendrochronology
Radiometric dating
Thermoluminescence
Physical structure of living beings depends on the protein
content in their bodies. The changes in this content help determine the relative age
of these fossils.
Amino acid dating
Dendrochronology
Radiometric dating
Thermoluminescence
This technique solely depends on the traces of radioactive
isotopes found in fossils. The rate of decay of these elements helps determine their
age, and in turn the age of the rocks
Amino acid dating
Dendrochronology
Radiometric dating
Thermoluminescence
Which geological dating technique determines the actual age of a fossil?
absolute
radioactive isotopes
relative
stratigraphy
Which geological dating technique arranges them in the geological order of their formation?
absolute
radioactive decay
radioactive isotopes
relative
It tells if an object/event is younger or older than another object/event from
history.
Relative Dating
Absolute Dating
It is qualitative methods of dating.
Relative Dating
Absolute Dating
Most absolute dates for rocks are obtained with radiometric methods.
Relative Dating
Absolute Dating
It is quantitative methods of dating.
Relative Dating
Absolute Dating
This technique helps determine the exact age of the remains.
Relative Dating
Absolute Dating
List down the Four (4) Eras of Geologic Time Scale in order from oldest to most recent.
The (a) is used as a record of the
major events and diversity of life forms present in
Earth’s history.
