It can take thousands of years for sand to form. That's because it forms when rocks break down and erode. Therefore, the exact composition of sand depends on which substances are present in the rocks. Rocks containing quartz (silica) take an exceptionally long time to erode. However, silica sand is the primary type of sand that is used to ...
