How Do You Learn The Age Of A Tree
The term used by the science world for tree ring dating is dendrochronology or the science of dating based on the growth of the ring patterns. This tree has 90 rings and has different ring sizes. Normally the rings are thicker in the middle and get skinner as the tree gets older. This is caused by the fact that the tree is young and grows faster in its youth than when the tree gets older. In some cases there can be some thicker rings in the older growth of the tree. There can be many causes for this, like greater rainfall for that year or greater sunlight on the tree.
As the tree gets older it gets larger and it looks as though its growing slower because the tree rings are thinner but if you think about it the trees circumference is increasing every year so it takes more cells to lay down the same growth as the year before.
