Question

Quizplus · Accepted Answer

Seawater is a solution consisting of water and various dissolved salts, gases, and other substances. It is not pure water and has a complex chemical composition that varies spatially and temporally. The salinity of seawater is high, typically ranging from 35 to 40 parts per thousand. Seawater is also denser than freshwater due to its higher salinity and temperature, and it exhibits stratification with increasing depth.
