tree-rings
Trunk age markers
Tree-rings are the concentric circles visible in a cross-section of a tree trunk, each representing one year of growth.
Counting them reveals the tree's age; their width indicates growing conditions—wide rings suggest favorable years, narrow rings drought or stress.
The study of tree-rings (dendrochronology) helps date archaeological artifacts and reconstruct past climates.
