Absolute dating can be determined by which of the following select all that apply

46 10 months ago
Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element decays into a non-radioactive product at a regular rate. Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample.

Absolute Dating

Layers that are farther beneath the surface are usually older in relativity to the layers that are closer to the surface. Geologists look for index fossils, evidences of specific organisms that were widespread, rapidly evolving, plentiful, and only existed during a specific geologic time period. Trilobites are an example of one such index fossil. When an index fossil is identified in a rock layer, it can be assumed that the age of the rock falls within the time period of the organism's existence.
