During spring,summer and autumn,a tree grows a new layer of cells just below its bark.
These layers,called "growth rings"or"tree rings",are easy to see when a tree is cut down.
You can fine out how old the tree was by counting the rings,right down to the tiniest one in the center.
If you know when a tree was cut down,you can figure out what year it started.
