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 Earth's physical features, they both had limitations as well.Determine which of the two hypotheses would be able to explain......why the continents move.
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
