A tree is a woody perennial plant typically having a single stem or trunk growing to a considerable height and bearing lateral branches at some distance from the ground.
Why does trees have rings?
Growth rings are the rings inside a tree or any other living thing with similar features and marking. You can tell how old a tree is by its rings or how old a house is by the wood in the furniture or walls. Counting the growth rings of a tree is a way to tell how old a tree is.
There is usually a single ring added each year because of the transition between the growth of the previous year and the new growth.
Tree rings grow under the bark, and the bark is pushed out while the tree is growing. Growth rings are of different colours, some are lighter and thinner while others are darker and thicker.
All these differences tell us about how the grew throughout its life.
The inner part of a growth ring is formed early in the growing season when growth is fast and is known as early wood. The outer portion is the late wood, and is denser than the early wood. Many trees in places with hot summers and cold winters make one growth ring a year.
Some trees don’t appear to have rings at all, while other trees grow thousands of rings, if they live enough.
The Cambium is a part of a tree that forms these rings each year or in some speies, twice a year. If you peel back a trees bark, you will find a slippery surface. The cells are like building blocks that produce new layers of wood.
Tree rings patterns are affected by the following;
*.Climate
*.Weather
*.Rainfall
*.Temperature
*.Soil PH
*.Plant Nutrition
*.CO2Concentrtion and
*.Sunspots
A dry year may result in a very narrow ring. Trees from the same area, will tend to grow the same pattern of rings. Tree rings are used to make radiocarbonating more accurate.
