Vedclass · Answer

(A) Growth rings,also known as annual rings,are formed due to the differential activity of the vascular cambium throughout the seasons. In temperate regions,the cambium is more active in spring and less active in autumn,resulting in the formation of spring wood and autumn wood,respectively. Together,these two layers constitute one annual ring,which represents one year of growth. Therefore,by counting the number of annual rings in a tree trunk,the age of the tree can be determined.
