Which of the following conditions would cause the salinity of ocean water to decrease? a. high rates of evaporation b. melting of glaciers c. erosion of rocks and minerals d. the warming of ocean water.

The correct answer is B. Melting of glaciers. Glaciers are not salt water so adding them to the sea would reduce the salinity of the sea. Similar thing occurs when rivers flow into the sea or the ocean. Evaporating would make it more salty because the water would leave while salt would stay meaning there would be less water and more salt.
