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.
Salinity is the measure of all the salts dissolved in water. Salinity is usually measured in parts per thousand (ppt or). The average ocean salinity is 35ppt and the average river water salinity is 0.5ppt or less.This means that in every kilogram (1000 grams) of seawater, 35 grams are salt.Because the water in estuaries is a mix of fresh water and ocean water, the salinity in most estuaries is less than the open ocean.alinity is the measure of all the salts dissolved in water. Salinity is usually measured in parts per thousand (ppt or). The average ocean salinity is 35ppt and the average river water salinity is 0.5ppt or less.
