Dendrochronology (Identifying Oldness of Woods from Treerings), Reg EQROFAAJ

Описание: Dendrochronology.

Now you have a piece of Furniture, a table,
and you want to know how old it is.

It's an old table of a medieval Castle. Now, it's out of Wood.
And every time a Tree grows, it puts on a new layer, every year.

And if a Tree...
and every year it's one, so if a Tree has 100, it's 100 years old.
If it's 1,000 years old, it has a thousand of these.

And if it's a good year for the tree with perfect Sun,
but also enough Water to grow good,
not to get thirsty and something, then it grows a lot.

If it's a bad year with a lot of bad weather it grows only little.

So these Rings, are exactly one per each year of a Tree,
these layers.

And they're also sometimes better sometimes not so good.
They're bigger or smaller, and sometimes they have different coloring also and so on.

And now we taking our Piece of Wood.
We're looking there - (at) our Table - What Rings are there?
If it was made out of such a Piece of Wood
and looking at these Rings.

And if you see now 20 in one Row,
and there are three good, three bad, three bad, three good,
whatever,

and now we're taking a Piece of Wood from the same Region.

So we're taking now a Tree,
which had grown in the same Region as the Table.

A new tree and we look then in it,
when does that piece measure that Piece.

And from the tree, because it was still growing,
before we cutted it, we know
(that) the last layer is the year it is now.

So if we go now back until that piece of wood which we found in the table fits in. There you have it.

And then we can count back how many rings were added onto that piece since that piece was cutted out of it.
We know it is so and so old.|

Not cutted out of that Tree... but all the Trees in an Area
show the same Signs of a Rings;
because all the Trees had a good year or a bad year.

All the trees in a few Kilometers have the same amount of Rain and Sun and so on. So all trees have it.

And now we're having a similar Tree which has grown at the same Time as the other Tree - which we don't know of -
out of which the Table was made, we can find in that other Tree which had grown at the same time, there it fits that Table is exactly 500 years old or something.

And that is the Dendrochronology Method.
