What are annual rings how do they form?
When water is scarce, like in summer time, the cambium layer produces many small xylem (the plant "water pipes") to make it easier to draw water. when water is abundent, like in winter, there is no need for many small xylem and the cambium layer produes larger "pipes". since this process runs in a cycle every year annual rings are formed where in the dark area is where the numerous small "pipes" are and the light area is where the bigger ones are. since one ring is formed every year the number of rings equals the age of the tree. note that this only occors in a temperate climate where one has a seasonal cycle, in a tropical region when water availability is equal throughout the year trees do not form annual rings.zaf. In trees and other woody plants, this is the layer of wood produced each year that can be seen when the wood is cut into a cross section.
