Key demand of the question
The question expects us to explain the nature of variation of surface temperature of oceans across different regions of the world. Next, we need to explain the factors which affects these changes.
Structure of the answer
Introduction – Mention that like land masses ocean water varies in temperature from place to place both at surface level and at great depths.
- Explain the nature of variation of surface temperature of oceans across various regions. Mention that the annual range is somewhat smaller. Mention the variation with respect to latitudes. Examine whether the variation in temperature is uniform or whether it changes due to presence of certain factors. Discuss the variation in temperature in enclosed spaces.
- Discuss the factors affecting this variation. Discuss the variation in surface temperature with respect to depth, latitude, effect of ocean currents, enclosed spaces.
