Wegener noticed that fossils of the an extinct reptile, Mesosaurus, were found in areas of both South America and South Africa. This let him to conclude that

• South America and Africa must have been connected at one point

• Mesosaurus evolved two different times in two different continents

• There must be a large land bridge connecting the two continents

• Mesosaurus swam across the Atlantic ocean

Wegener compared how the coastlines of continents fit together like...

• Puzzle pieces

• A Monopoly board 

• Janga pieces 

• Two peas in a pod

The force that moves the tectonic plates is

• Convection currents in the ocean

• Wind in atmosphere pushing the continents on the mantle

• Convection currents in the Earth's mantle

• The continents float around randomly

Continental drift hypothesis was not considered a theory because

• People did not like Wegener

• It is not true

• During Wegener's lifetime there was not enough evidence for people to accept the idea

• Wegener falsified some of his data and because of this, his hypothesis was rejected
