California Beach Sand This typical California wave-washed beach sand is rich in quartz, which looks a bit like bits of glass under magnification. Assume the beach sand was sampled from Long Beach and is derived from rocks in the San Gabriel Mountains. Describe a plausible history of the beach sand. Start with weathering of the rocks in the San Gabriel Mountains. Consider which transporting agent(s) may have delivered the sediment to the ocean. Make sure to address changes to clast size and rounding that are likely to occur on such a journey.
