GEOLOGY

Detailed explanation-1: -Radiometric dating. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes.

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: -One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains. This is a radiometric technique since it is based on radioactive decay.

Detailed explanation-4: -Answer and Explanation: Absolute dating is more accurate than relative dating because it uses the known decay rates of unstable isotopes to determine the age of rock or organic material with a much narrower range of age than relative dating.

Detailed explanation-5: -Scientists commonly use a combination of relative and absolute dating methods to determine the age of a given stratum and the fossils it contains. RELATIVE DATING relative age-older or younger-is based on the location where a given fossil occurs in a layered sequence of sedimentary rocks.
