Question

question 4 (multiple choice worth 2 points)
how did wegeners theory of continental drift differ from the current theory of plate tectonics?
wegeners theory did not explain how the continents could move.
wegeners theory did not explain how the coastlines of continents were similar
wegeners theory did not explain how continents rock patterns could match
wegeners theory did not explain how the fossils on different continents were similar

Explanation:

Wegener proposed the idea of continental drift but lacked a mechanism for how continents moved. Plate - tectonics theory later provided the mechanism of convection currents in the mantle. Similar coastlines, rock patterns, and fossil distributions were evidence for continental drift proposed by Wegener.

Answer:

Wegener's theory did not explain how the continents could move.
