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.
In the open ocean the range of salinity is generally from 32 psu to 37 psu. Along with temperature, it is a major factor in contributing to changes in the density of seawater and therefore ocean circulation. Salinity is the key to understanding the global water cycle. 97% of the Earth's free water resides in the oceans. The water cycle is dominated by precipitation and evaporation.
