The Scientist Who Mapped the Seafloor: Marie Tharp | Great Minds

The video discusses the significant contributions of Marie Tharp to oceanography, particularly her role in mapping the ocean floor and discovering the mid-Atlantic ridge. Her work provided evidence for the theory of continental drift, challenging the prevailing expanding Earth hypothesis. Despite initial skepticism, Tharp's maps and the correlation with earthquake epicenters confirmed the movement of tectonic plates. Her legacy continues to influence our understanding of the Earth's geological processes.
