Answer: evaporation, ice melting, precipitation, and ice formation.
Step-by-step explanation:
Salinity refers to the amount of salt water that can be found in a body of water.
It should be noted that the salinity of a water body can be affected by evaporation, ice melting, precipitation, and ice formation.
The salinity of seawater can be increased through evaporation due to the fact that when the water evaporates, this will lead to the salts being left behind, and this will then increase the salinity.
