Explanation:
Detailed explanation-1: -Scientists can learn more than a tree’s age by counting its rings. By looking closely at the rings’ structure and size, they can determine what the weather was like as the tree grew. Thick rings indicate years of rapid growth due to plenty of water. Thin rings indicate periods of drought.
Detailed explanation-2: -Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood.
