question 4 of 25\nhow is absolute dating used to find the ages of fossils?\na. it involves using index fossils and their locations in rock to estimate the ages of other fossils.\nb. it involves calculating the amount of a radioactive isotope in a sample and comparing it with the amount of a stable isotope.\nc. it involves comparing the amount of uranium - 235 in a fossil with the amount of carbon - 14 in the fossil.\nd. it involves using the principle of superposition to find the ages of fossils found in earth’s rock layers.

Answer

Brief Explanations:

El datado absoluto utiliza la desintegración radioactiva. Calcula la cantidad de un isótopo radioactivo en una muestra y lo compara con la cantidad de un isótopo estable. Esto se basa en las constantes de decaimiento de los isótopos. Las otras opciones describen métodos diferentes de datación, como el datado relativo (usando fósiles índice y superposición).

Answer:

B. It involves calculating the amount of a radioactive isotope in a sample and comparing it with the amount of a stable isotope.
