Often starting thousands of miles from the ocean, rocks slowly travel down rivers and streams, constantly breaking down along the way.

    How sand is found on a beach?The sand found on a specific beach is created by its surroundings. It’s unique to that beach—like a fingerprint. Most beaches get their sand from rocks on land. Over time, rain, ice, wind, heat, cold, and even plants and animals break rock into smaller pieces. This weathering may begin with large boulders that break into smaller rocks.
    Where does sand come from?The sand found on beaches primarily comes from the erosion of rocks and coral reefs. Erosion and weathering of rocks on land forms particles that rivers carry to the sea. Waves and tides gradually break down these materials into finer particles.
    What is sand made of?Sand, 2nd Edition. W H Freeman & Co. Sand is composed of sand grains which range in size from 1/16 to 2 mm. Sand grains are either mineral particles, rock fragments or biogenic in origin.
    What type of sand is found in inland environments?In terms of sheer size, sand grains lie somewhere between silt and gravel. The most common constituent of sand found in inland environments is silica (silicon dioxide – SiO-2), which is usually in the form of quartz. Another very common type of sand consists of calcium carbonate (e.g., aragonite), which forms over a period of millions of years.
