• पेड़ की उम्र कैसे पता करते हैं ? How is the age of tree estimated ?

  In this episode we learn about rings of tree, and how to estimate a tree age by its rings. Most of us learned as children that the age of a tree could be found by counting its rings. Rings of trees growing in temperate climates can indeed tell their age through their annual rings and also help determine the age of wood used to construct buildings or wooden objects. The ages of wooden objects can be revealed by cross-dating, the process of matching ring patterns between wood samples of known and unknown ages.
