Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology derives from Ancient Greek dendron (δένδρον), meaning "tree", khronos (χρόνος), meaning "time", and -logia (-λογία), "the study of".

Tree rings are created by the tree as it grows in girth, and the width of a given tree ring is dependent on climate, so a stand of trees will all have a near-identical pattern of tree rings. Counting tree rings is one of the most accurate ways to determine a tree’s age. In order to do so, you need to find the stump of a tree that has been cut down or get a cross-section of wood from near the bottom of the tree that shows all the rings. Once you understand how to count the pattern of rings, it’s very easy to … See more flash drives large capacity
