Cross-bedding

Cross-bedding refers to layers of sediment that are inclined at an angle within a larger bed, formed by the movement of wind or water. As currents or winds carry particles, they create inclined surfaces or limbs, which record the direction and strength of the flow. These features often appear as angled layers in rocks and can indicate past environments such as deserts, rivers, or beaches. Cross-bedding provides valuable clues about ancient climate, water flow patterns, and sediment transport, helping geologists interpret Earth's geological history accurately.
