Continental Drift Hypothesis

Wegener used evidence of glaciers in places now too warm as evidence to support his hypothesis of Continental Drift.

• true

• false

What discovery revived Wegener's idea of Continental Drift and eventually led to the Theory of Plate Tectonics?

• discovery of new fossils on Africa and South America

• the discovery of mid-ocean ridges and seafloor spreading

• the discovery of radioactive isotopes

• none of the above

Why was the evidence of seafloor spreading so important to the idea of Continental Drift?

• it answer the question for HOW continents could be moving

• it disproved Alfred Wegener's hypothesis of Continental Drift

• It shows how land bridges let prehistoric animals cross the oceans

• all of these are true

What technological advances led to the acceptance of Wegener's Contienental Drift hypothesis?

• sonar and magnetometers mapped the ocean floor

• satellite communication allowed scientists to share ideas

• computers were used to model tectonic patterns

• fossils of the same organism were found on separate continents

Who was the scientist who came up with the continental drift hypothesis?

• Charles Darwin

• Alfred Wegner

• Isaac Newton

• Albert Einstein

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

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

Which of the following are pieces of evidence that support the contintal drift hypothesis, that we read about in class. (2)

• Mountain ranges in the United states, match up with those in Europe.

• Evidence of glaciers in places where glaciers should not have existed at that latitude

• Discovery of a massive land bridge connecting the United States and Africa

• Evidence that the gravity of the moon influenced the movement of the tectonic plates
