The sand on California beaches primarily originates from the erosion of coastal cliffs and mountains, as well as from river systems that transport sediments to the ocean. Over time, waves and currents break down rocks and pebbles into smaller particles, which accumulate on the shoreline. Additionally, the sand can be influenced by human activities, such as construction and mining, which may alter the natural sediment flow. This dynamic process continually reshapes the beaches along the California coast.
