Dendrochronology

/ˌdɛndroʊkrəˈnɒlədʒi/ noun

Definition

The science of dating events and environmental conditions by studying the annual growth rings of trees.

Etymology

From Greek 'dendron' (tree) + 'chronos' (time) + 'logos' (study). Trees record history in their rings — droughts, fires, volcanic eruptions, all visible in wood.

Kelly Says

Trees are HISTORY BOOKS! Each ring is a year, and thin rings mean drought, thick ones mean good years! Scientists can read tree rings like DIARIES going back thousands of years! 🌳📖
