Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is knowing the age of something in comparison to other things?
A
carbon dating
B
relative dating
C
vestigial
D
DNA studies
Explanation: 

Detailed explanation-1: -Relative dating methods estimate whether an object is younger or older than other things found at the site. Relative dating does not offer specific dates, it simply allows to determine if one artifact, fossil, or stratigraphic layer is older than another.

Detailed explanation-2: -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-3: -Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e., estimated age).

Detailed explanation-4: -Scientists also tried to use relative dating techniques to determine the age of the planet. Stratigraphy compares the configuration of layers of rock or sediment in order to determine how old each layer is in relation to one another.

Detailed explanation-5: -The Principle of Cross-cutting Relationships: Rocks that cut across formations are younger than the rocks they cut across. The Principle of Inclusions: Inclusions within rocks are older than the surrounding rock. The Principle of Baked Contacts: Rocks with heat markings are older than igneous rock.
