annual ring
Trunk growth band
Annual ring refers to a layer of wood produced by a tree during one year's growth, visible as a concentric circle in a cross-section of the trunk.
Counting annual rings reveals a tree's age; their width indicates growing conditions—wider rings suggest favorable years, narrower ones drought or stress.
Also called growth ring or tree ring.
