Detailed explanation-1: -Dendrochronology is the study of the rings of the tree. The rings are present on the cross section of the trunk, the tree age can be determined by counting of these concentric rings.
Detailed explanation-2: -The girth of a tree can be used to estimate its age, as roughly a tree will increase it’s girth by 2.5cm in a year. So, simply measure around the trunk of the tree (the girth) at about 1m from the ground. Make sure you measure to the nearest centimetre. Then divide the girth by 2.5 to give an age in years.
Detailed explanation-3: -So, the correct option is ‘Dendrochronology’.
Detailed explanation-4: -By counting the number of annular rings, it is possible to know the age of a plant. This study is known as dendrochronology.
