7.10AB Plate Tectonics & Continental Drift

What was the problem with Wegener's Theory of Continental Drift?

• It could not explain what caused the continents to move

• He falsely stated that matching fossils were found on different continents

• He couldn't show evidence of matching rock formations

• The idea of the Earth being a puzzle was too outrageous to accept

Which is NOT evidence used to support the Theory of Plate Tectonics?

• Some continents have similar coastlines to each other

• Fossils of the same animals were found on different continents

• Some animals used land bridges to travel between continents

• There was evidence of glaciers found in areas that are now very warm
