Answer 1

The correct response is: Earth’s crust is made of plates that move.

During Wegener's time, the concept of plate tectonics, which explains the movement of the Earth's crustal plates, was not known. While Wegener presented evidence for continental drift, the understanding that Earth's crust consists of moving plates came later, with the development of plate tectonic theory in the mid-20th century.
