Continental Drift

Note: Our world today is actually a 2’nd or 3’rd generation “super continent” or “pangea” !!!

Paleo-glaciation! Refers to the study of Old Glaciers Found in Africa!!!

Wegener’s idea of continental drift (1930) was rejected…. People said…if “continental drift” is true…..explain how it occurs! Where is the proof ????

oUoZAUg&feature=related oUoZAUg&feature=related

This is called “Sea Floor Spreading”

KU&feature=related KU&feature=related

Paleomagnetism and Sea Floor Spreading explains continental drift! (and why ….. A) why fossils on both sides of the ocean are the same B) why mountain ranges on both sides of the ocean are the same C) why rocks are the same on both sides of the ocean D) why coal is found in the Antarctic E) why paleoglaciation explained rock scrapings in Africa Continental Drift!!!! --- The slow movement of continental plates caused by sea floor spreading over hot, rising magma (liquid rock)
