Describe the Great Lakes - St. Lawrence landform region (Geography)

The Great Lakes are located near the border between the United States and Canada. The total area of the lakes is 244,106 km².   The land around the lakes is rich in minerals such as iron ore, nickel, copper, lead, zinc, gold, silver and asbestos. The lakes are of great importance for the transport of coal.  The lakes were carved out by the ice sheet that covered most of the Northern Hemisphere during the last glacial period. In winter, the surface of the Great Lakes creates the Lake Effect, and the resulting Snow Belt stretches across five states.

wow this is so hard for me im only in elementry school still!

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.
