The four elements that make up most of the mass of the Earth's oceans are hydrogen, oxygen, sodium, and chlorine. Hydrogen and oxygen combine to form water (H₂O), which constitutes the majority of ocean mass. Sodium and chlorine primarily exist as dissolved salts, contributing to the salinity of seawater. Together, these elements play a crucial role in the chemical composition and physical properties of ocean water.
