Incremental dating techniques allow the construction of year-by-year annual chronologies, which can be temporally fixed (i.e., linked to the present day and thus calendar or sidereal time) or floating.
Archaeologists use tree-ring dating (dendrochronology) to determine the age of old pieces of wood. Trees usually add growth rings on a yearly basis, with the spacing of rings being wider in high growth years and narrower in low growth years. Patterns in tree-ring growth can be used to establish the age of old wood samples, and also give some hints to local climatic conditions. This technique is useful to about 9,000 years ago for samples from the western United States using overlapping tree-ring series from living and dead wood.

Answer:
D. the law of crosscutting relationships
Explanation:
The law of cross-cutting relationships can help explain the age of the rock as it relates to the surrounding rock.
This law is one of the premise of relative dating. The relationship between the intrusion and rock body or country rock is used to discern their age.
- When intrusions cross-cuts the host rocks, they are usually younger.
- The host rock must haven emplaced before the intrusion sets in
- The intrusion utilizes weak planes within the rock body to cool and solidify.
- Now, when they are emplaced, then a vein or other intrusive bodies forms.
