The main difference between different types of sand is in its composition. Commonly found sand includes quartz, feldspar, and mica, while volcanic sand contains minerals such as olivine and magnetite. Silt and clay particles can also be present in some types of sand. Additionally, sedimentary sand is composed of grains that have been eroded from rocks or other sources, while beach sand is made up of particles that have been deposited by waves.
