The mineral found in large quantities in the ocean is sodium chloride, commonly known as salt. Ocean water contains about 3.5% dissolved salts, with sodium chloride being the most abundant. This mineral plays a crucial role in regulating oceanic processes, influencing marine life, and maintaining countless ecosystems. In addition to its biological significance, seawater's salinity is essential for various industries, including food preservation and water treatment. Evaporation from the ocean can also lead to salt formations on land, contributing to its availability for human use.
