NEET BIOLOGY

Detailed explanation-1: -Relative age dating is used to determine whether one rock layer (or the fossils in it) are older or younger than another base on their relative position: younger rocks are positioned on top of older rocks.

Detailed explanation-2: -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-3: -In geology, absolute dating can tell us the approximate age in years of the rock. The main way absolute dating is carried out is by Radiometric dating.

Detailed explanation-4: -The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectrometer.

Detailed explanation-5: -Radiometric dating. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks.
