1. What is the scientific theory?Continental drift, integrated into the theory of plate tectonics
2. What is the key proponent?Alfred Wegener (early 20th century)
3. Who first thought continents might move?The idea goes back to the 16th century with Abraham Ortelius, but it was Alfred Wegener in the early 1900s who made a strong case that all continents were once joined together in a supercontinent called Pangaea.
4. How do scientists know the continents have moved?Scientists look at matching coastlines, identical fossils on now‑separated lands, similar mountain ranges that line up when continents are put together, and clues from old glaciers and coal beds that show continents were once in different climates.

Pangaea: A hypothetical supercontinent that existed during the late Paleozoic and early Mesozoic eras.
Lithosphere: The rigid outer part of the Earth, consisting of the crust and upper mantle.
Mantle Convection: The slow circulation of rock within Earth's mantle, driven by heat, that moves tectonic plates.
