Which of the following is related to relative dating dating coimbatore woman

Long before geologists tried to quantify the age of the Earth they developed techniques to determine which geologic events preceded another, what are termed "relative age” relationships.

These techniques were first articulated by Nicolas Steno, a Dane living in the Medici court of Italy in the 17th C.

Different species of ammonites lived at different times within the Mesozoic, so identifying a fossil species can help narrow down when a rock was formed.

Relative dating does not provide actual numerical dates for the rocks.

Fossils are important for working out the relative ages of sedimentary rocks.

Numerical dating determines the actual ages of rocks through the study of radioactive decay.

Relative dating cannot establish absolute age, but it can establish whether one rock is older or younger than another.

Suppose you find a fossil at one place that cannot be dated using absolute methods.

That fossil species may have been dated somewhere else, so you can match them and say that your fossil has a similar age.

Some fossils, called index fossils, are particularly useful in correlating rocks.

For a fossil to be a good index fossil, it needs to have lived during one specific time period, be easy to identify and have been abundant and found in many places. If you find ammonites in a rock in the South Island and also in a rock in the North Island, you can say that both rocks are Mesozoic.

Throughout the history of life, different organisms have appeared, flourished and become extinct.
