Which type of dating technique results in a numerical age of a rock layer?
A
relative age dating
B
absolute age dating
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

Detailed explanation-2: -One of the most useful absolute dating methods for archaeologists is called radiocarbon dating. It works by measuring carbon isotopes, which are versions of the element carbon. All isotopes of carbon have 6 protons but different numbers of neutrons.

Detailed explanation-3: -Of the three basic rock types, igneous rocks are most suited for radiometric dating. Metamorphic rocks may also be radiometrically dated. However, radiometric dating generally yields the age of metamorphism, not the age of the original rock.

Detailed explanation-4: -Numerical dating is the process of applying techniques of physics and chemistry to rock sequences to establish an absolute “numerical age” for the time of formation. (2) Fundamental laboratory and empirical observations of time-related chemical and physical phenomena must be established.

Detailed explanation-5: -Thermoluminescence Dating: Thermoluminescence allows scientists to determine how old something is by the amount of radiation energy that emanates from it. Radiocarbon Dating: Radiocarbon dating is a type of absolute dating that measures various versions of carbon, known as carbon isotopes. More items •29-Jun-2022
