Why did people not believe in Wegener's theory about continental drift?

• There was a competing theory at the time that was more believable.

• There was no data showing the continents ever moved.

• The scientists did not know the force responsible for moving the continents.

• The scientist presenting the data was unreliable.

How did fossil evidence support Wegener's hypothesis of continental drift?

• Similar fossils are found along continental margins that appear to join together.

• Fossils are found in areas where present-day climate could not have supported the organisms that made the fossils.

• Similar fossils of land-dwelling dinosaurs are found on continents separated by oceans.

• All of the above.
