Kasvuasteilla

Kasvuasteilla, also known as growth rings or annual rings, are concentric layers of wood formed in the trunk of a tree. Each ring represents one year of the tree's life, with the width of the ring indicating the amount of growth during that year. The outer part of the ring, known as the earlywood, is formed during the spring and summer months when the tree is actively growing. The inner part of the ring, known as the latewood, is formed during the fall and winter months when growth is slower. The transition between earlywood and latewood can be quite distinct, creating a visible boundary within the ring. The number of growth rings can be used to determine the age of a tree, with each ring corresponding to one year of growth. This technique is commonly used in dendrochronology, the science of dating and studying past climates using tree rings. The study of growth rings can also provide insights into the environmental conditions a tree experienced during its lifetime, such as periods of drought or favorable growing conditions.
