growth ring
Woody annual layer
A growth ring is one of the concentric circles visible in the cross-section of a tree trunk, each representing a year's growth.
Counting rings reveals the tree's age; their width indicates growing conditions—wider rings suggest favorable years, narrower ones drought or stress.
Also called an annual ring or tree ring.
