den·dro·chro·nol·o·gy

(dĕn′drō-krə-nŏl′ə-jē) The study of annual rings in trees in order to analyze past climate conditions or to determine the date of past events. Trees grow more slowly in periods of drought or other environmental stress than they do under more favorable conditions, and thus the annual rings they produce are smaller. By observing the pattern formed by a tree's rings, scientists can learn about the environmental changes that took place during the period in which it was growing. They can also match up the pattern in trees whose age is known to the pattern in a piece of wood found at an archaeological site, thereby establishing the approximate date of the site.
