What is Dendrochronology?Slide4
Trees grow in both height and width.
The xylem tissue in trees conducts water and dissolved nutrients from the soil throughout the entire tree
Tree Rings are formed in the Xylem layer each growing season
Each Annual Ring has aSpring RingThicker because there is more water presentSummer RingThinner and darker in colour because there is less water and the growing xylem cells are smaller

Cool stuff Trees have Told us
The analysis of the oak planks making up one Viking
Longship
(found in Norway) showed that the wood was from trees cut down near Dublin, Ireland some time between AD 1060-1070.
Discovered in Norway in 1906, the
Oseberg
ship, the best preserved Viking ship ever found, reveals its Norse shipbuilders' graceful construction style.
