Continental Drift

It was a supercontinent, made of all of the landmasses on Earth.

It was 2 separate landmasses, one on the Northern Hemisphere and one on the Southern Hemisphere.

It was a supercontinent made of 3 landmasses

It was the name of an ancient organism

Continents and fossils fitting together/matching-up like puzzle pieces

tropical rain forests were found in different locations

divergent boundaries were found in different locations.

sea floor spreading caused new crusts to be formed.

the mesosaurus fossils were found on both continents

He noticed that similar rocks were found on both continents

he thought that the continents used be be joined together

Pangaea was 250 million years ago

Same rocks and mountain ranges were found on different continents

Glacial grooves were found on different continents

Fossilized evidence of the same organism found on different continents

Africa and South America look like puzzle pieces that fit together

Same rocks were found on different continents

Glacial grooves were found on different continents

Fossilized evidence of the same organism found on different continents

Africa and South America look like puzzle pieces that fit together

Glacial grooves were found on different continents

Africa and South America look like puzzle pieces that fit together

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.

The present continents will gradually move to form a single landmass called Pangaea.

The continents were once a large landmass name Pangaea, which broke apart and gradually drifted to the present-day locations of the continents.

The continents were once a large landmass, but the north and south magnetic poles pulled the continents apart toward the poles

The continents were once a large landmass, but the ocean levels rose, and these oceans separate today's continents.

This evidence shows that the two continents have similar landforms.

This evidence shows that the mountains contain fossil evidence.

This evidence shows that sea-floor spreading occurs, and magnetic reversal patterns exist on the sea floor.

This evidence shows that they were once a single mountain range when the continents were connected and were later separated as the continents drifted apart.
