Most of the Earth's salt water is found in the oceans, which cover about 71% of the planet's surface. The average salinity of ocean water is around 3.5%, primarily due to the presence of dissolved salts, predominantly sodium chloride. Additionally, salt water can also be found in seas, estuaries, and some salt lakes, but the vast majority resides in the oceans.
