Test: Continental Drift - Question 1
Save

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

Detailed Solution: 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
Save

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

Detailed Solution: 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
Save

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

Detailed Solution: 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
Save

What did Wegener propose as the reason for the equatorward drift of continents?

Detailed Solution: 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
Save

What was the primary criticism of the Continental Drift Theory related to the forces causing the drift?

Detailed Solution: 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
Save

Which force did Wegener suggest was responsible for the westward drift of continents?

Detailed Solution: Question 6

Alfred Wegener proposed that the continents drifted across the Earth’s surface due to forces such as tidal drag caused by the Moon and the Sun. However, scientists later showed these forces were far too weak to move continents, which was one reason his theory was initially rejected—even though the idea of continental drift itself was later validated through plate tectonics.

Test: Continental Drift - Question 7
Save

What evidence supported the idea that South America and Africa were once joined together, according to Wegener?

Detailed Solution: 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
Save

What was Wegener's explanation for the separation of North America and South America from Europe and Africa?

Detailed Solution: 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
Save

Which region does not exhibit evidence of Permo-Carboniferous glaciations, as pointed out in the criticism of Wegener's theory?

Detailed Solution: Question 9

Wegener’s theory of Continental Drift was supported by geological evidence such as the presence of Permo-Carboniferous glacial deposits in now widely separated southern landmasses, suggesting they were once joined in a supercontinent called Gondwana.

Regions that do show Permo-Carboniferous glacial evidence:

  • South Africa – clear evidence of ancient glaciation
  • Indian Peninsula – Gondwana glaciation deposits found, especially in the Gondwana coal fields
  • Falkland Islands – show geological similarities and glacial deposits matching other Gondwana regions
  • But,Brazil – largely lacks significant evidence of Permo-Carboniferous glaciation. This was pointed out by critics of Wegener who noted inconsistencies in glacial distribution.

Therefore, Correct Answer - Option C

Test: Continental Drift - Question 10
Save

What was one of the criticisms of the Continental Drift Theory related to the lithosphere and asthenosphere?

Detailed Solution: 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.
