Make sure you are able to answer questions on:

 1. explain with the aid of an annotated diagram, why Tropical latitudes receive more of the sun’s energy than Polar regions  2. explain why there is a net gain of solar region in the Tropical latitudes and a net loss towards the poles  3. describe the role of atmospheric circulation in the redistribution of energy over the globe.  4. describe and explain the earth’s energy exchanges shown on a diagram  5. describe and account for the generalised pattern of atmospheric circulation and global winds, **or** ocean currents shown on a world map

 6. describe and explain the origin, nature and weather characteristics of Tropical Maritime (mT) and Tropical Continental (cT) air masses which affect West Africa  7. with reference to the Inter-Tropical Convergence Zone and the movement of air masses, describe and account for the variations in West African rainfall.
