Theoretical predictions suggest that the North Pole should be cooler than it actually is. What helps to warm regions at high latitudes? The Earth's tilt on its axis means that for half the year the temperatures at the North Pole will increase. The heat-carrying capacity of water takes warm water toward the poles with ocean currents, and warms some northern regions. Warm air from the equator moves toward the poles before descending. There is a large amount of ice, and the ability of water held in the ice to resist temperature changes means it holds a lot of heat.

answer; ///i believe the correct answer to the above question is; ///(drainage basin;

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.

d is the logical answer but im not a 100% sure
