Dendrochronology By Nicky
In this video you learn what makes the rings on a tree so important and how to date it back to when it was first planted.
Did you know Dendrochronology can only take us back approximately 11,500 years? Or that you can daisy-chain your way back theoretically for millions or years using petrified forest? Cool eh.
Oldest tree alive to have been cored.
Basin bristlecone pines, Pinus longaeva. Did you know they are the oldest living trees dated by dendrochronology? They dont look so impressive, do they?
My "top five" reasons for believing in a young earth.
"I would like to discuss the next set of data that leads me to believe in a young earth: dendrochrology. This is just a fancy word for counting tree rings, and it probably represents the most reliable way to date things for which there is no historical date available. This reasonably accurate dating method once again gives us strong evidence for a very young earth.
Let’s start with the basics. In the spring, a tree does a lot of growing, since conditions are ideal for such activity. As a result, the new wood is not very dense. As spring turns to summer and summer to autumn, growth slows down. As a result, the wood becomes more dense. A typical turn of the seasons, then, produces light, not-so-dense wood followed by dark, dense wood. This produces a visible ring. Thus, in general, each year results in a ring. So if you cut down a tree, by counting the rings, you can determine how old the tree is."
