The correct response is:

**Earth’s crust is made of plates that move.**

During Wegener's time, the theory of plate tectonics, which explains that the Earth's crust is made up of moving plates, had not yet been developed. Wegener proposed the idea of continental drift, but did not have the mechanisms to explain how continents could move across the Earth's surface.

The correct response is:

**Africa and South America.**

The coastlines of Africa and South America show a fit, and there are also similarities in their mountain ranges and geological features, which supports the idea of continental drift.
Answered by GPT-4o mini
The correct response is:

**subduction.**

Scientists observed subduction occurring in the Pacific Ocean, where one tectonic plate is being forced under another, leading to the conclusion that the Pacific Ocean is becoming smaller as its plate is subducted back into the mantle.

The correct response is:

**Pangaea.**

Pangaea was the supercontinent that existed during the late Paleozoic and early Mesozoic eras and included all of Earth's current continents.
