List several factors that cause salinity to vary from place to place and from time to time

What will be an ideal response?


Variations in salinity are primarily a consequence of changes in the water content of the solution. Processes that add large amounts of fresh water to seawater—and thereby decrease salinity—include precipitation, runoff from land, icebergs melting, and sea ice melting. Processes that remove large amounts of fresh water from seawater—and thereby increase seawater salinity—include evaporation and the formation of sea ice. High salinities, for example, are found where evaporation rates are high. Conversely, where large amounts of precipitation dilute ocean waters, as in the midlatitudes and near the equator, lower salinities prevail.
