Growth rings are a unique feature of trees that provide valuable information about their lifespan, growth rate, and environmental conditions. Each year, a tree forms an annual growth ring, which represents the increase in its diameter due to growth that year. This growth pattern is determined by factors such as climate, soil type, and light exposure, among others. Through studying the growth rings of trees, we can gain insights into the history of the environment in which they grew, and thus gain a better understanding of the natural world around us.
