Beach sand

Beach sand is made up mostly of tiny particles formed from the erosion of rocks and shells, primarily quartz and carbonates. These grains are shaped by natural forces like wind and waves, which round their edges. The color and composition of beach sand can vary greatly depending on the local geology, with some beaches having white, golden, or even black sand. Beaches are dynamic environments where sand is constantly moving due to tides and currents, playing a crucial role in coastal ecosystems and protecting shorelines from erosion. Overall, beach sand is both a natural resource and a popular attraction.
