Detailed explanation-1: -The concentration of salt in seawater (its salinity) is about 35 parts per thousand; in other words, about 3.5% of the weight of seawater comes from the dissolved salts.

Detailed explanation-2: -The term “salinity” refers to the concentrations of salts in water or soils. Salinity can take three forms, classified by their causes: primary salinity (also called natural salinity); secondary salinity (also called dryland salinity), and tertiary salinity (also called irrigation salinity).

Detailed explanation-3: -Salinity is the accumulation of salt in land and water to a level that damages the natural and built environment. Many parts of the Australian landscape are naturally salty but human activities can cause salt levels to rise.

Detailed explanation-4: -Salinity-Salinity is the amount of salt in grams present in 1000 grams of water. The average salinity of the oceans is 35 parts per thousand.

Detailed explanation-5: -Salinity (/səˈlɪnɪti/) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity).
