An annual ring, also known as a growth ring, is a layer of wood added to a tree's trunk each year. It's like a birthday cake for trees πβeach ring tells you how old the tree is. The width of the ring can also tell you about the growing conditions that year. Wide rings usually mean a good year with plenty of rain and sunshine βοΈ, while narrow rings indicate a tough year with drought or disease. By studying annual rings, scientists can learn about past climates and environmental changes.
