What are the main components of ocean water?

The main components of ocean water include water, salts, dissolved gases, and organic materials. Water, constituting the largest part of ocean water, serves as the solvent in which various substances are dissolved. Salts, primarily sodium chloride, are present in significant concentrations and contribute to the ocean's salinity. Dissolved gases, such as oxygen and carbon dioxide, are vital for marine life, affecting respiration and photosynthesis processes. Organic materials, which include microorganisms and decomposed plants and animals, play a critical role in the marine ecosystem, serving as a source of nutrients for various organisms. This combination of components is crucial for maintaining the ocean's chemical balance and supporting diverse marine life.
