Question
A cross section of tree trunk contains 60 lighter and 60 darker rings. Determine the age of the tree and justify
Solution
In the cross section of the tree trunk, the lighter (spring wood) and darker (Autumn wood) rings appear in the form of concentric circles. Thus one dark and one light ring would have been formed every year. 60 dark and 60 light rings indicate the age of the tree as 60 years.
