Test: Continental Drift - Question 1

What feature along the coasts of the Atlantic Ocean intrigued Wegener and led to the idea of continental drift?

Detailed Solution for Test: Continental Drift - Question 1
Wegener was intrigued by the "Jigsaw Fit," the apparent geographical fit between the opposite coasts of the Atlantic Ocean. The outlines of the east coast of North and South America seemed to fit into the west coast of Africa and Europe.
Test: Continental Drift - Question 2

What did Alfred Wegener name the single supercontinent in his Continental Drift Theory?

Detailed Solution for Test: Continental Drift - Question 2
Alfred Wegener named the single supercontinent in his Continental Drift Theory "Pangaea," derived from the Greek words "pan" meaning all and "Gaea" meaning earth.

Test: Continental Drift - Question 3

Which climatic evidence was crucial for Wegener's theory of continental drift?

Detailed Solution for Test: Continental Drift - Question 3
The presence of tropical ferns in regions like London, Paris, Bonn, and Greenland was a climatic anomaly that Wegener used as evidence for continental drift.
Test: Continental Drift - Question 4
What did Wegener propose as the reason for the equatorward drift of continents?
Detailed Solution for Test: Continental Drift - Question 4
Wegener attributed the equatorward drift of continents to the rotation of the Earth and its equatorial bulge, influencing the movement of landmasses.
Test: Continental Drift - Question 5
What was the primary criticism of the Continental Drift Theory related to the forces causing the drift?
Detailed Solution for Test: Continental Drift - Question 5
One of the primary criticisms of the Continental Drift Theory was the controversial nature of the forces Wegener suggested as causing the drift, particularly the impact on Earth's rotation and atmosphere.
Test: Continental Drift - Question 6
Which force did Wegener suggest was responsible for the westward drift of continents?
Detailed Solution for Test: Continental Drift - Question 6
Wegener proposed that the westward drift of continents was influenced by the gravitational pull of the moon and the sun.
Test: Continental Drift - Question 7
What evidence supported the idea that South America and Africa were once joined together, according to Wegener?
Detailed Solution for Test: Continental Drift - Question 7
Geological structure, such as the similarity in rocks and mountains, provided evidence that South America and Africa were once joined together. The Appalachian mountains in North America and the Hercynian Mountains in Europe display this geological resemblance.
Test: Continental Drift - Question 8
What was Wegener's explanation for the separation of North America and South America from Europe and Africa?
Detailed Solution for Test: Continental Drift - Question 8
According to Wegener, the separation of North America and South America from Europe and Africa was due to westward drift, influenced by the gravitational pull of the moon and the sun.
Test: Continental Drift - Question 9
Which region does not exhibit evidence of Permo-Carboniferous glaciations, as pointed out in the criticism of Wegener's theory?
Detailed Solution for Test: Continental Drift - Question 9
Wegener's theory faced criticism regarding the Permo-Carboniferous glaciations, especially in explaining the presence of evidence in regions like Brazil, which is not in proximity to polar regions.
Test: Continental Drift - Question 10
What was one of the criticisms of the Continental Drift Theory related to the lithosphere and asthenosphere?
Detailed Solution for Test: Continental Drift - Question 10
The criticism of "Sial Floating Over Sima" suggests that the lithosphere (continental crust or sial) floating over the asthenosphere (mantle or sima) may not fully explain the complexities of tectonic processes and landmass movement.
