During the eighteenth and nineteenth centuries, the \"contracting Earth model\"

Question

During the eighteenth and nineteenth centuries, the "contracting Earth model" hypothesis attempted to explain the origins of Earth's physical features by assuming that the Earth has been slowly cooling and contracting since its formation. A few scientists still supported the contracting Earth model when Alfred Wegener proposed his continental drift hypothesis in the early twentieth century. While both hypotheses were able to explain the origins of some of the Earth's physical features, they both had limitations as well.

Determine which of the two hypotheses would be able to explain...

...the presence of mountain belts.

Question 27 options:

Contracting Earth model only

Continental drift hypothesis only

Both the contracting earth model and continental drift hypothesis

Neither the contracting earth model nor the continental drift hypothesis

Continental drift and seafloor spreading

A)

Contracting Earth model only

B)

Continental drift hypothesis only

C)

Both the contracting earth model and continental drift hypothesis

D)

Neither the contracting earth model nor the continental drift hypothesis

Explanation / Answer

27)...the presence of mountain belts.

Answer is: B

Continental drift hypothesis only

Explanation:

Wegener use to support the hypothesis of continental drift  observation as Mountain belts match across continental margins.

40) Which two ideas were combined to form the theory of plate tectonics?

Answer is:

c) Continental drift and seafloor spreading

Explanation:

By combining the sea floor spreading theory with continental drift and information on global seismicity, the new theory of Plate Tectonics became a coherent theory to explain crustal movements.

Wegener use to support the hypothesis of continental drift  observation as Mountain belts match across continental margins.
