Answer» - The surface temperature of sea water is not uniform everywhere and it changes with latitudes.
- The surface temperature of the seawater decreases from the equatorial areas towards the poles.
- The average temperature in equatorial areas is around 25° C, it is 16° C in mid-latitudes while it is about 2° C near the poles.
- Besides this, cyclones, rainfall, sea waves, ocean currents, salinity, pollution, convergence flow, seasons, etc. also affect the surface temperature.
- Thus the surface temperature of the sea is not uniform everywhere.
