Ice core sampling normally uses the assumption that the ring bands observed represents years.

Relative dating does not provide actual numerical dates for the rocks.Seriation uses the assumption that once a tool was developed, its use would become more widespread.Stratigraphy uses the assumption that higher layers or strata were laid down after lower layers. ANSWER: Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.This technique does not give specific ages to items.During the First Jewish Revolt against Rome (66–70 C.

E.), which ended with the destruction of the Temple, Jews minted their own coins dated to the first, second, third, fourth and, more rarely, even fifth year of the revolt.

Climate chronology uses evidence of a climatic change, such as an ice age, as a benchmark for dating.

states, “Before the 20th century, archaeologists and geologists were largely limited to the use of relative dating techniques.

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.

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.

This matching process is called correlation, which has been an important process in constructing geological timescales.
