ocean chemistry

Ocean chemistry involves the study of the chemical composition and processes within seawater. The ocean is primarily made up of water molecules, but also contains salts like sodium and chloride, making it salty. It includes dissolved gases such as oxygen and carbon dioxide, which are vital for marine life. The balance of these chemicals affects the ocean's health and influences climate, marine ecosystems, and ocean acidity. Factors like volcanic activity, freshwater input, and biological activity constantly change ocean chemistry, making it a dynamic and essential component of Earth's system.
