The ocean salinity depends on evaporation and precipitation: High evaporation increases salinity by removing water. High precipitation decreases salinity by adding fresh water. This statement is correct.<br \/>\n2. Any change in the temperature or density influences the salinity: Temperature affects the rate of evaporation and ice formation (brine rejection), thus influencing salinity. Density is determined by temperature and salinity. Changes in density (e.g., due to temperature changes) can cause water masses to move, influencing the distribution of salinity through mixing and circulation. This statement is correct.<br \/>\n3. Major source of sea salinity is terrestrial discharge by rivers: Rivers carry dissolved salts and minerals from the land, derived from the weathering of rocks, into the oceans. This continuous input over geological time is the primary reason for the ocean&#8217;s saltiness. This statement is correct.<\/section>\n<section id=\"pyq-additional-information\">Other contributions to sea salinity include volcanic outgassing, dissolution of seafloor rocks, and hydrothermal vents, but riverine input is the most significant source of dissolved solids.<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Consider the following statements relating to Sea Salinity : 1.
