tengervízi

tengervízi is the Hungarian word for seawater. It refers to the saline water found in oceans and seas. The composition of seawater is complex, containing a variety of dissolved salts, gases, and organic matter. Sodium chloride is the most abundant salt, contributing significantly to the characteristic salty taste of the sea. Other dissolved ions include magnesium, sulfate, calcium, and potassium.

The salinity of seawater can vary depending on factors such as evaporation rates, freshwater input from rivers and precipitation, and the degree of ice formation. Open ocean waters typically have a salinity of around 35 parts per thousand (ppt), meaning there are 35 grams of dissolved salts per kilogram of seawater. Coastal areas and enclosed seas can exhibit different salinity levels. For instance, the Baltic Sea is less saline due to significant freshwater inflow, while the Red Sea is more saline due to high evaporation rates and limited freshwater input.

Seawater plays a crucial role in regulating Earth's climate through ocean currents, which distribute heat around the globe. It is also a vital habitat for a vast array of marine life, supporting diverse ecosystems from coral reefs to the deep ocean trenches. Human activities, such as pollution and overfishing, can impact the health and composition of seawater, highlighting the importance of its conservation.
