Areas with heavy freshwater runoff and low evaporation will have lower than average salinity.
Explanation:
Runoff is the terminology used in hydrology that defines the flow of water that occurs on the soil surface when it is saturated with moisture. When water reaches the earth's surface some of the water seeps into the soil and the amount of surplus flows to the surface. The amount of water that drains depends on some factors, such as rainfall intensity and soil infiltration capacity. This process has a significant effect on the physical properties of this area, such as salinity, pH, and other factors. However, we can conclude that areas with heavy freshwater runoff and low evaporation will have lower than average salinity, due to the constant dilution of salts by the constant presence of water.
