Wegener found fossils of land reptiles on two different continents. This was important because

• Land reptiles are often found all over the world, showing that they can survive in most climates

• Land reptiles cannot swim, so the continents must have been connected for them to get across

• Land reptiles are never moved around the Earth by humans, so they must have travels to these continents by themselves

• Land reptiles fossilized much better than other animal species

Wegener found fossils of ancient ferns on Antarctica, this shows

• That some ferns can survive temperatures well below freezing

• That humans put ferns on Antarctica millions of years ago

• That Antarctica drifted from a warmer climate where plants could grow

• That fossils can be formed in cold climates

How was Wegener's theory received by other scientists at the time?

• They thought it was great

• They did not accept it

Why was Wegener's hypothesis not accepted?

• He could not explain what force was moving the continents

• He was a meteorologists, so no one took him seriously

• He did not have enough types of fossils to support his theory

• Because scientists thought Harry Hess' theory was better
