Explanation:

Pangaea was a supercontinent that existed millions of years ago. It was a single large landmass. Tectonic plates are the moving pieces of the Earth's lithosphere. The highest mountain on Earth is Mount Everest. A theory about the Earth's inner core would be related to geological theories about the core's composition, temperature, etc. But Pangaea specifically refers to the ancient single continent.

Answer:

A single continent on Earth millions of years ago.
