Concentric Circles of Friendship

Tree Rings Circles Illustration

Concentric circles are seen in nature, such as ripples in a pond, the layers of an onion, and the rings of a tree. Interestingly, the rings of a tree, much like the concentric circles of friendship, provide a historical account of the conditions the tree experienced. “Tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry. If the tree has experienced stressful conditions, such as a drought, the tree might hardly grow at all in those years” (Jessica Stoller-Conrad, “Tree Rings Provide Snapshots of Earth’s Past Climate,” Global Climate Change, NASA, January 25, 2017, Our circles shape us also.
