The main difference between salt water and fresh water is the salinity content. Both contain salt or sodium chloride, but fresh water contains only small amounts of salt. The earth’s oceans and seas are saltwater ecosystems, while lakes, rivers, streams, marshes and ponds are freshwater ecosystems. Seawater’s viscosity, or internal resistance to flow, is higher than fresh water because of differences in salinity.Know More
The average salinity of ocean water is 3.5 percent which means that 35 grams of salt dissolve in a liter of seawater. The salinity of different bodies of water hinder organisms from thriving in both salt water and fresh water. Some plants and animals survive in one type of water but not the other.
Another considerable difference between the two is their density. Salt water has a higher density than fresh water because of the sodium chloride it contains. Furthermore, cold salt water is denser than warm salt water, but it becomes less dense when water freezes into ice. The boiling point of seawater is higher than that of pure water, and its freezing point is lower. The density of salt water is 1.025, while fresh water’s density is 1.0. Objects float more easily in salt water than in fresh water. Humans typically find it easy to float in seawater but not in fresh water.Learn more about Natural Resources
Rock salt comes from deposits found around dry lake beds, inland marginal seas and enclosed bays and estuaries. It can also be found in salt springs and underground mines.Full Answer >
The main difference between a canal and a river is that a river is a natural flow of water while a canal is man-made. A river by definition flows from inland into the sea while a canal is most often constructed to connect existing rivers, lakes or oceans.Full Answer >
Drinkable water can be obtained from seawater by removing salt through a distillation process. Distillation is a simple process that can be done on a small scale as a personal project or on a large scale as a desalination plant that provides drinking water for many. Despite its simplicity, desalination is an expensive process compared to getting drinking water from fresh water sources.Full Answer >
The difference between salt and sugar, specifically sodium chloride and sucrose, the particular salt and sugar most often used by people, is in their elemental composition, the types of bonds that hold them together and the way they dissolve in water. Salt and sugar can appear almost identical on casual inspection, both being white, crystalline solids. However, despite the fact that both are water soluble, they have vast chemical differences.Full Answer >
