Question

how can we know the age of the tree?​

Answer 1

there are two ways to find out how old a tree is. The first one is to wait until the tree is cut down and count the rings. The second is to use an increment borer and count the rings on a trunk cross section. The study of tree rings to calculate a trees' age is called dendrochronology.

Answer 2

Answer:

If you know when the tree was planted, you can easily and accurately determine its age. The second most accurate way to estimate tree age is to count the annual rings of wood growth. Annual rings can be counted using two different methods. You can extract an increment core from the tree using an increment borer.
