Exploring Continental Drift in Plate Tectonics

The video explores the revolutionary concept of plate tectonics, which transformed our understanding of Earth's dynamic nature. It delves into the theory of continental drift proposed by Alfred Wegener, who suggested that continents were once a single landmass called Pangaea. Despite initial skepticism, Wegener gathered evidence from fossil records, rock formations, and climate data to support his theory. Although he never saw his ideas fully accepted, his work laid the foundation for modern geology.
