Answer Details
The scientist who proposed the theory of continental drift was Alfred Wegener.
Wegener was a German geophysicist who lived in the early 20th century. He noticed that the shapes of the continents on either side of the Atlantic Ocean looked like they could fit together like pieces of a puzzle. He also observed that there were similar rock formations and fossils found on opposite sides of the ocean.
From these observations, Wegener hypothesized that the continents were once joined together in a single landmass he called "Pangaea" and over time, they drifted apart to their current positions. This hypothesis later became known as the theory of continental drift.
However, Wegener's theory faced significant opposition from the scientific community at the time, as there was no known mechanism for how the continents could move. It was not until decades later, with the discovery of plate tectonics, that Wegener's theory was finally widely accepted as the scientific explanation for the movement of Earth's continents.
