Arbor Day Foundation on Instagram: "We all know that tree rings can tell a tree's age, but they can tell us SO much more. A tree's light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring + one dark ring = 1️⃣ year of a tree’s life. Rings also give scientists information about that area’s local climate in the past. Tree rings usually grow wider in warm, wet years and they are thinner
