Trees of the World - Tallest, Widest and Oldest trees in the World
In countries that do not have tropical weather the age of trees can be found out when they fall over. This can be done by counting the number of rings on the trunk. Each ring is one year of the trees life. By looking at the rings you will see they get fatter and thinner. The thinner parts of the ring show the slow growth of winter. The fatter parts of the ring show the spring and summer months where it grew a lot.
