Trees in places with clear seasons grow one ring each year, so by counting the rings you can find out the age of the tree. Also, the rings vary in thickness depending on the weather, so by matching the wide/narrow sequence from a known tree to an unknown sample of wood it's possible to tell the age of the unknown sample.

What is denrochronology?
the analysis of tree rings and dating trees according to their rings.
Counting tree rings to determine the age of a tree is an example of dating?
Yes, counting tree rings to determine the age of a tree is an example of dendrochronology, which is a method used to date trees by analyzing their growth rings. Each ring represents one year of growth, allowing scientists to estimate the age of the tree.
Can radiocarbon dating be used to find the age of a tall tree?
Radiometric dating, specifically carbon dating, can be used to find the age of an old tree. In the past, cutting a tree down and counting rings was the method used to get to the innermost material of a tree. Then you could count the rings. Presently, the inner regions of old and valuable trees are regularly sampled with a coring tool that extracts a small cylinder of material without killing the tree. One can count the rings with the core, and that is most common. (This is not unlike the idea behind ice cores.) Using the core for radiometric dating is more tedious, but may be needed if something about the growth pattern leaves ring counting undesirable. It is interesting to note that in the past, carbon dating was calibrated using data from tree rings but now the process is reversed.
What kind of dating is counting tree rings an example of?
Incremental
What absolute dating technique has been used to calibrate radiocarbon dates?
Dendrochronology, or tree-ring dating, has been used to calibrate radiocarbon dates. By matching the pattern of tree rings in an archaeological sample with a master chronology, scientists can improve the accuracy of radiocarbon dates.
In addition to dating and correlation tree rings can also be used to make interpretations about past?
Yes, the width between the rings indicates what kind of weather it's been that year.
What kind of dating is dendrochronology considered to be?
Dendrochronology is a method of dating based on the analysis of tree-ring patterns. It is used to determine the age of wooden objects or structures, as well as to study past climate conditions and environmental changes.
How does dendrochronology assist radiocarbon dating?
Tree rings provided truly known-age material needed to check the accuracy of radiocarbon dating as a method. During the late 1950s, several scientists (notably the Dutchman Hessel de Vries) were able to confirm the discrepancy between radiocarbon ages and calendar ages through results gathered from radiocarbon dating tree rings dated through dendrochronology. Today, tree rings are still used to calibrate radiocarbon determinations. Libraries of tree rings of different calendar ages are now available to provide records extending back over the last 11,000 years. Source: http://www.radiocarbon.eu/tree-ring-calibration.htm
What have tree rings been used to measure?
The age of a tree.
How do you spell dendochronology?
Based on the Greek word for "tree limb", the spelling is dendrochronology (dating tree age by rings).
When we cut the log of a tree horizontically the rings are seen what the rings indicates?
The rings on the inside of a tree indicate how old the tree is. For example, if the tree had sixteen rings then the tree would be sixteen years old, and so would have been growing for sixteen years.Additional. Dendrochronology is the science of dating tree rings, and can extend back to over 25 000 years. Without error, for parallel patterns of growth in various fossil (often swamp) trees are quite usable.
How can we tell how old a tree a rock and a horse is?
1. The age of a tree can be determined by counting the annual rings (cambiam rings in dicotledons). 2. The age of a horse is determined by the number of teeth 3.The age of rocks can be determined by carbon dating.
