What does the theory of continental drift state?

What evidence did Wegener use in his theory?

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

• glacier scars and evidence from climate

• mountain ranges and coal deposits line up across continents

• Land bridges that connected the continents

Why did no one believe Wegener's thoery?

• He could not explain HOW the continents moved

• He didn't have evidence

• His data was wrong

• He didn't use the right technology to gather data

What two specific continents fit together most noticeably?

• Africa and North America

• South America and Europe

• South America and Africa

• Antartica and Africa

According to the continental drift hypothesis, the presence of similar fossils in South America and Africa supports which scientific idea?

• Animals easily and frequently travel from Africa to South America.

• Species of animals probably traveled between continents on natural rafts (such as trees destroyed in tsunamis).

• Land bridges once existed that connected the continents.

• South America and Africa were once connected together.

According to the continental drift hypothesis, the presence of similar mountain ranges in North America and Europe supports which scientific idea?

• Mountains can easily and frequently travel between North America and Europe

• Mountains probably enjoy swimming (but only once every 250 million years).

• Land bridges once existed that connected the continents.

• North America and Europe were once connected together.

According to the continental drift hypothesis, the presence of similar glacial scrapings on multiple continents supports which scientific idea?

• That glaciers love warm locations and summertime just like Olaf.

• In the past glaciers must have extended from the poles to the equator.

• Glaciers are so cool that they can not be bound by the laws of thermodynamics.

• In the past landmasses like India must have been located closer to the poles.
