If you were to analyze the sand on a typical beach along the Atlantic coast, you would find that most of the sand grains are composed of the mineral quartz. In contrast, if you analyzed sand on some beaches in Hawaii, you might find that the dominant grains contain minerals such as pyroxene or olivine. Quartz, pyroxene, and olivine are all silicate minerals. Use weathering processes to explain why the compositions of these beaches differ.
