What can be recognized by the tree rings?

A tree ring is a layer of wood that forms in one season. Its formation is associated with the division of cambium cells. They actively divide in spring and summer; by autumn, the division and growth of the resulting cells slows down, and in winter it stops altogether. Therefore, a border is formed that separates one layer from another.

By the number of rings on the stump of a cut tree, you can find out its age; by their width – which years in his life were favorable and which were not. Finally, the large width of each ring on the south side.
