Detailed explanation-1: -These rings can tell us how old the tree is, and what the weather was like during each year of the tree’s life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall.
Detailed explanation-2: -Tree rings form in the trunk of a tree from new cells generated in the cambium, the meristem (growing point) that lies just beneath the tree’s bark. In the early part of the growing season when the tree is emerging from dormancy and growing conditions are near perfect cells grow rapidly and are less dense.
Detailed explanation-3: -Each year, the tree forms new cells, arranged in concentric circles called annual rings or annual growth rings. These annual rings show the amount of wood produced during one growing season.
Detailed explanation-4: -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.
