This educational vintage-style tee features a detailed rock cycle diagram illustrating the transformation between magma, igneous rock, sedimentary rock, metamorphic rock, and sediment. Rendered in muted green ink on a crisp white shirt, the retro scientific illustration captures the timeless beauty of geology and Earth science with a lightly distressed classroom-chart aesthetic. Made from 100% ring-spun cotton (high-quality cotton) with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
