Give geographical reason:The surface temperature of the sea is not uniform everywhere.

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.
