Written Test No. 4 in Earth Science

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
