1912, Alfred Wegener proposed the idea of continental drift. This idea stated that Earth’s continents were once joined as a single landmass, as shown in the illustration. Wegener believed that over time, this landmass broke into pieces that drifted apart to form the continents as they are known today. Although Wegener had evidence to support his idea, most scientists rejected the idea of continental drift because they could not explain how it occurred. Today, however, the theory of continental drift is widely accepted by scientists. Which of the following explains how the theory of continental drift came to be widely accepted? A. More information was discovered about the rock cycle.
B. The law of superposition was developed.
C. The theory of plate tectonics was developed.
D. The law of uniformitarianism was applied more widely.
