Counting rings in wood
WebTree rings: Trees add a new layer of wood every year. When you cut across the trunk, each layer looks like a ring. Each ring represents one year. Rings generally grow wider in warm, wet years and thinner in cold, dry years. Tree ring records can go back hundreds to thousands of years, depending on when the tree lived and how old it was. WebBy counting the number of rings of wood (called Annual Rings) in a trunk or in a branch, you can tell how many years that part has been growing. You then know the age of that part of the tree. The age of the lower trunk would be the same as the age of the whole tree. Some tree rings are wide and some are narrow.
