1. the taste experience when common salt is taken into the mouth. 2. the relative proportion of salt in a solution.
Seawater typically has a salinity of around 35 g/kg, although lower values are typical near coasts where rivers enter the ocean. Rivers and lakes can have a wide range of salinities, from less than 0.01 g/kg to a few g/kg, although there are many places where higher salinities are found. Red colors represent areas of high salinity, while blue shades represent areas of low salinity. It is important to understand salinity, the amount of dissolved salts in water, because it will lead us to better understanding of the water cycle and can lead to improved climate models. Synonyms: salinity; saltiness; salt. Hypernyms (salinity is a kind of...): gustatory perception; gustatory sensation; taste; taste perception; taste sensation (the sensation that results when taste buds in the tongue and throat convey information about the chemical composition of a soluble stimulus). The noun SALINITY has 2 senses: 1. the taste experience when common salt is taken into the mouth. 2. the relative proportion of salt in a solution. Familiarity information: SALINITY used as a noun is rare. Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ions. Red colors represent areas of high salinity, while blue shades represent areas of low salinity. It is important to understand salinity, the amount of dissolved salts in water, because it will lead us to better understanding of the water cycle and can lead to improved climate models. Split and merge into it. Answer by Roy Forssberg. Confidence votes 36.3K. Salinity is the saltiness or dissolved salt content of a body of water. Salinity in Australian English and North American English may also refer to the salt in soil. Salinity is the amount of salt in something. So, dry land salinity is the amount of salt in the dry land involved. Salinity is the saltiness or dissolved salt content of a body of water (see also soil salinity). Red colors represent areas of high salinity, while blue shades represent areas of low salinity. It is important to understand salinity, the amount of dissolved salts in water, because it will lead us to better understanding of the water cycle and can lead to improved climate models. This salinity measurement is a total of all the salts that are dissolved in the water. Although 35 parts per thousand is not very concentrated (the same as 3.5 parts per hundred, o/o, or percent) the water in the oceans tastes very salty. The most important components of seawater that influence life forms are salinity, temperature, dissolved gases (mostly oxygen and carbon dioxide), nutrients, and pH. Each of these is discussed below along with how it varies (or does not vary) and its influence on marine life. Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean. As soil salinity increases, salt effects can result in degradation of soils and vegetation. Salinization as a process can result from: 1  high levels of salt in water. 2  landscape features that allow salts to become mobile (movement of water table). Salinity. Although everyone knows that seawater is salty, few know that even small variations in ocean surface salinity (i.e., concentration of dissolved salts) can have dramatic effects on the water cycle and ocean circulation. Throughout Earth's history, certain processes have served to make the ocean salty. Red colors represent areas of high salinity, while blue shades represent areas of low salinity. It is important to understand salinity, the amount of dissolved salts in water, because it will lead us to better understanding of the water cycle and can lead to improved climate models. Salinity is the measure of all the salts dissolved in water. Salinity is usually measured in parts per thousand (ppt or). The average ocean salinity is 35ppt and the average river water salinity is 0.5ppt or less. This means that in every kilogram (1000 grams) of seawater, 35 grams are salt. Because the water in estuaries is a mix of fresh water and ocean water, the salinity in most estuaries is less than the open ocean.
