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.
High concentrations are also in sub-tropical regions due to high rates of evaporation (clear skies, little rain, and prevailing winds) and in landlocked seas in arid regions. At high latitudes, salinity is low. This can be attributed to lower evaporation rates and the melting of ice that dilutes seawater.To sum up, salinity is low where precipitation is greater than evaporation, mainly in coastal or equatorial regions.hroughout Earth's history, certain processes have served to make the ocean salty. The weathering of rocks delivers minerals, including salt, into the ocean. Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean.
