Deriva continental

The video discusses the concept of continental drift, first proposed by Alfred Beguenner in 1912. He suggested that continents move across the planet, supported by fossil similarities in West Africa and Eastern South America. Initially, the idea was not widely accepted until the 1950s, when upward convection currents from magma beneath the Earth's surface provided a plausible mechanism.
