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.
When fresh water is added for example by rivers, or precipitation, the salinity of the ocean will decrease. That explains why some oceans are less salty than others Factors like the melting of ice, the inflow of river water, rain, snowfall, evaporation, wind, wave motion and currents affect the salinity. cubic foot of seawater contains about 2.2 pounds of salt, but 1 cubic foot of fresh water from Lake Superior contains 0.01 pound of salt, or about one sixth of an ounce. That means sea water is about 220 times saltier than a fresh water lake.
