Salt Water vs. Fresh Water: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 8, 2023
Salt water contains significant amounts of dissolved salts, mainly found in oceans, while fresh water has minimal salt content, typical in rivers and lakes.

Key Differences

Salt water, comprising about 97% of Earth's water, is characterized by its high saline content, primarily found in oceans and seas. Fresh water, making up a mere 3% of Earth's water, has a significantly lower salt concentration, predominantly present in rivers, lakes, and glaciers.

The salinity of salt water, around 35 parts per thousand (ppt), makes it unsuitable for human consumption without desalination, while fresh water, with less than 1 ppt of salt, is vital for human consumption, agriculture, and most industrial uses.

Marine life adapted to salt water often cannot survive in fresh water due to differences in osmoregulation and vice versa, whereas fresh water supports a different set of aquatic life forms, adapted to its low salinity environment.
