Question 9 • TPS EdX Biology

Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift?

Answer
A
The continents were once connected as one landmass.
B
The continents have moved apart very quickly due to earthquakes.
C
The continents are magnetically pulled toward or pushed away from one another.
D
The continents drifted apart due to repeated meteor impacts.

Explanation

Wegener proposed that Earth’s continents were once joined together in a single landmass, which he called Pangaea, and later drifted apart. The statement that the continents were once connected describes this idea; earthquakes, magnetic forces, and meteor impacts were not his explanation for continental drift.
