The main difference between different types of sand is their size and composition. Sand can be classified into three categories: quartz, feldspar, and carbonate. Quartz sand has a high content of silicon dioxide and is usually white or grey in color. Feldspar sand consists of potassium, sodium, calcium, aluminum, and other elements. It is usually light brown or tan in color. Carbonate sand contains magnesium, iron, and other minerals and is usually dark gray or black in color. Additionally, sand may also have organic materials such as plant debris and shells mixed in with it.
