What do we gain by understanding oceans? Of the different branches of ocean study (biological - studying life in the oceans, chemical - studying ocean chemicals and how it interacts with the atmosphere, geological - studying the plate tectonics of the ocean floor, and physical - studying the waves, tides and currents) which do you think is the most important? Which would you be most interested in studying if you decided to enter an oceanography school? What questions would you want to answer as part of your study in that program?

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.
