SSC Selection Post 2024 PYQ — Question 28

Atmospheric pressure is the force exerted by the weight of the air above a given point. It primarily depends on factors like altitude, temperature, and humidity, which affect the density and amount of air molecules. Ocean salinity, on the other hand, influences seawater density, ocean currents, and evaporation rates. While atmospheric pressure can affect ocean salinity (e.g., high pressure leading to higher surface salinity due to increased evaporation), ocean salinity itself does not determine the atmospheric pressure above it.
