Question

For half of the radioisotopes of a certain kind to decay into its more stable isotope, the amount of time required is called the _______. Radiocarbon dating is typically used to date more recent objects like _______, cloth, wood, and plant fibers. _______ rocks cannot be accurately dated using isotopic dating because this rock type is formed through the sedimentation of different rocks and mineral fragments. Using the principle of faunal succession, scientists can determine the age of rocks by the _______ embedded within them.

Answer 1

For the half of the radioisotopes of a certain kind to decay into more stable isotope, the amount of time required is called The Half Life.

Radiocarbon dating is typically used to date more recent objects like bones, cloth, wood, and plant fibers.

Sedimentary rocks cannot be accurately dated using isotope dating because this Rock type is formed through the sedimentation of different rocks and minerals fragment.

Using the principle of faunal succession, scientist can determine the age of rocks by the fossil flora and fauna embedded within them.

Step-by-step explanation:

Carbon dating is a process which is done by the use of carbon 14 atom. It is a special type of atom which can easily help the scientist and expert to find out the age of the fossil of flora and fauna, rocks, animals, birds, etc.

Answer 2

half-life

bone

sedimentary

fossils

Relative dating is used to determine the age of a rock, fossil, or mineral in relation to some other reference sample. Meanwhile, absolute dating is used to determine the age of a rock relative to the date of the test. Absolute uses isotopic methods, while relative dating uses stratigraphic methods.

The Paleozoic era lasted from 540 Ma to 251 Ma, so 87Rb should be used to date this fossil. 14C has a short half-life and is only accurate for dates up to 60 ka. 87Rb has a longer half-life, so it can be used to determine older dates.
