Answer:-
Continental Drift Theory was proposed by Alfred Wegener in 1912, suggesting that Earth's continents were once a single landmass, Pangaea, and have since drifted apart. He based this idea on matching fossils, rock formations, and coastlines across continents. However, he lacked a mechanism to explain how they moved, so the theory was initially rejected. Later, plate tectonics provided evidence that Earth's crust is divided into moving plates, driven by mantle convection. Today, Wegener's theory is widely accepted as the foundation of modern geology, explaining earthquakes, mountain formation, and the shifting of continents over millions of years.
