The telephone was promoted on the grounds that it would increase wealth, employment and improved means of communication. The invention of the telephone lead to development of city centers, office buildings and the concept of an urban worker society. It has lead to the creation and destruction of jobs. The need for positions such as messenger boys, telegraphers and, ironically, operators, became virtually unnecessary (Bauer, 1995).
Answers. Best Answer: Evaporation will increase salinity, the water will evaporate but the salt will remain so the concentration goes up. Ocean water will become less saline near rivers which are adding fresh water to the ocean. Melting glaciers and rainfall will add fresh water also and decrease the salinity.
1 Salinity is approximately equal to the weight, in grams, of salt dissolved in 1000 g of seawater. 2  This would be the salt concentration in parts per thousand 3  (). Average ocean water has a salinity of 35.0. 4  This means that 1000 g of average seawater contains 965 g of water and 35 g of salts.t has roughly 2/3 the salt content of regular seawater. Ocean salinity (expressed in-per mil) is approximately equal to the weight, in grams, of salts dissolved in 1000g of seawater. This would be the salt concentration in parts-per-thousand ().
