The Rings Are Formed By Ice And Rock. How They Where Formed Im Not Quite Sure, But Ice And Rock And The Reason They Are There. Dont Know If That Answers your Question, But I'd Like To Think It Did. :D xx
The thicker the tree ring the more tropical climate they lived in. The thinner the tree ring the colder and drier the climate was. 80,000,000 years ago tropical trees lived in Greenland. This tells us that Greenland was a tropical island 80,000,000 years ago.
If the rings of a tree are far apart, then the tree received plenty of water and nutrients that year, and the temperature was suitable for the tree to thrive, because the cambium layer of the tree was able to produce more cells, making more wood in between rings. If two rings are very close together, then the tree either did not have enough water, the temperature was too cold or too hot, or both, because the cambium layer did not produce as many cells, meaning less wood in between rings.
The rings in a tree trunk are referred to as secondary growth. This is when the tree grows outward, rather than upward. The rings form once a year.
The rings of the tree die or form new rings
The xylem.
Tree rings or annual rings tell how old the tree is.

They give how old the tree is. Like if the tree has 800 rings, it is 800 years old. how many rings determine how old the tree is.
the rings on the top section of a tree trunk tell the age of the tree
Dendrochronology is the study of the age and history of a tree and includes the study of tree rings.
There are naturally occurring rings, like tree rings and the rings of Saturn.
Tree rings are the sign of the age of the tree. Each ring is laid down each year.
The oldest living tree to be dated by counting rings is the bristlecone pine.
