Did you know .....?
 

So far, we can mengatahui how old someone asked him directly, but what if we wanted to see how old an object that can not speak such as trees, animals and more. Is it possible we could mengatahui old are they? Or do we have to learn the language of animals and trees so that we can mengatahui old are they? of course not .... the above questions we can answer without having to study the language of animals or trees.

The researchers have studied and learned how to measure or known age of a tree and animal. For example if we wanted to see how old a tree, then we need not bother to learn their language, just by looking at the base of a tree that was in pieces we can mengatahui how old they are. When a tree trunk grows it will be higher and greater, So it is with a circle or a ring in it will increase each year. then to calculate how much a ring or circle in which we can mengatahui how old a tree because of the ring indicates a year of tree age and color ring / circle every year has perberbedaan.
not just the trees that we know how long they have lived on the surface of our planet but animals can we know how old they are among others; sheep by measuring how many rings are gored, fish with megukur how the ring is in fins and many more.
Good luck ........!
