Tree stump. Cross section of a tree stump showing the circular bands of growth rings. Also seen is the tree's outer surface (bark). Each of the growth rings represents a year of growth for the tree. Counting these rings reveals the tree's age at felling. The rings can also give information on environmental conditions at the time of growth | |
