Each ring marks an entire cycle of seasons, or one year, within the tree's life. Hence 23 rings shows 23 years of trees life . Measurement of tree rings are based on Radiocarbon dating. 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.
