what does continental sized glaciers have to with evidence supporting plate tectonics? plz explain?

Answer 1

Well, simply put, in order to have glaciers to cover continents you must have that continent in a place where the glacier can form. That is, a continent would have to be in a different position (closer to a pole) in order to support a large glacier. Therefore, to do so, the continent must have moved.

Answer 2

There have been large glacial events that occurred in the past. Interestingly, sediments from those glaciation are found on continents now separated by great distances, but the evidence (such as ice flow directions, materials in the glacial deposits) suggest that the now-widely separated areas were once in very close proximity. This works particularly well with one involving antarctica, africa, and australia (and I think maybe also South America but I honestly don't remember). This is taken as pretty good supportive evidence that plate movement has occurred since that particular glacial event. It is just another line that supports plate migration and the whole concept of plate tectonics.
