Answer 2

Sand forms when rocks break down from weathering and eroding over thousands and even millions of years . Rocks take time to decompose especially quartz (silica) and feldspar. Often starting thousands of miles from the ocean , rocks slowly travel down rivers and streams, constantly breaking down along the way.
