Why Is the Ocean Salty

The ocean is salty because of the continuous movement of water over rocks and minerals on land. Rainwater, which is slightly acidic, erodes rocks, releasing minerals such as sodium and chloride into rivers that eventually flow into the ocean. Over millions of years, these minerals accumulated, making the ocean salty. Volcanic activity and hydrothermal vents on the ocean floor also contribute dissolved minerals, further increasing salinity.

How Ocean Salinity Affects Marine Life

The salt content of seawater plays a crucial role in supporting marine ecosystems. Many ocean organisms have adapted to specific levels of salinity, which helps regulate buoyancy, osmosis, and metabolic processes. Ocean currents, influenced by differences in salinity and temperature, drive global climate patterns and help distribute nutrients. Despite its high salt concentration, scientists are developing desalination technologies to convert seawater into freshwater, providing a potential solution for water shortages in many parts of the world.
