Fresh Water
Similarities
The greatest similarity between fresh and salt water is that both are basically the same chemical - water, although the contents of other materials dissolved in it differ.
Both contain some amount dissolved chemical in it though the quantities vary.
Both form different links in the water cycle of the nature.
Both are homes to aquatic life.
Difference:
Salt water contains much higher quantities of dissolved chemicals as compared to fresh water. This higher concentration of chemical also raises the density of salt water above that of fresh water.
Plant and animals living in two types of water bodies are different.
Salt water is found only as large standing bodies of water. Most of these are in form of seas and oceans, although though some lakes including very large ones considered to be sea also contain salt water. Fresh water is found in standing bodies of water called lakes, as well as running water as in rivers and streams. Fresh water is available in many other forms such as in rain, and ice caps in the poles and in very cold places. However no fresh water is found in seas and oceans.
Fresh water is used for drinking as well as many industrial processes. However salt water is generally not suitable for most of the industrial use except for cooling. On the other hand salt water is used as a source of some chemicals, particularly common salt. Freshwater does not yield any such chemicals.Comparing Fresh water and ocean water, each has their differences.
Most notable is animals living in each. The animals that live in the Salt "ocean" water would not survive in fresh water for an extended length of time. Same holds true for fresh water animals. However there are a few species that have adapted and can live in both. Some Salt water animals have also evolved to live in Fresh water.
Humans cannot drink ocean water without dying. The salt in it dehydrates you to the point you die of thirst. In order to drink ocean water you
