• Salinity is the measure of the dissolved salt content in a body of water.

The factors that influence salinity are:

• Freshwater input - Rivers, rainfall, and melting ice add freshwater to the ocean, which dilutes the salt content, thereby decreasing salinity.

• Evaporation - When water evaporates, the salt is left behind, increasing the concentration of salt in the remaining water. This increases salinity.
