What is the theory of plate tectonics? Distinguish among continental drift, seafloor spreading, and plate tectonics. What evidence was used to support the theory of plate tectonics?

Continental drift is a hypothesis that suggests that earth's continents move over time. Seafloor spreading is a theory that states that new ocean crust forms along mid-ocean ridges. Evidence to support plate tectonics includes magnetic studies of the seafloor, satellite imaging, & seismic studies.

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.
