"Dendrochronology or tree-ring dating is the method of scientific dating based on the analysis of tree-ring growth patterns. This technique was invented and developed during the 20th century originally by A. E. Douglass, the founder of the Laboratory of Tree-Ring Research at the University of Arizona. The technique can date wood to exact calendar years."

Yes, not only does each ring represent one year of aging, but it also tells you what that year was like. If the ring is really thick then the tree grew really fast, if they are small then the tree grew really slow. You can guess what the weather conditions were like that year just from the rings. Foresters have an interesting device for pulling a core sample from a tree so that they can count its rings without hurting the tree.

"Yep" ! Neat huh...?
You can also tell what the weather was like by the growth of the
tree, dry - very little growth, wet - thick growth ring. If you go to
a lumber yard, just take a look at the sides of a, let's say, 2x4.
You will notice rings in the wood. Sometimes they have wood boards cut so that the rings show up on the top of the wood.
Its really something to see.

yes it is
rings on the trees trunk forms annually
and if the tree is cut you can see the
rings and if there are 50 rings then the tree is 50yrs old.
