Central Ideas and Details Question 6:
The theory of continental drift, proposed by Alfred Wegener in 1912, suggests that continents are not stationary but move across the Earth's surface. Wegener's hypothesis was initially dismissed by the scientific community due to a lack of convincing evidence and a plausible mechanism. However, the discovery of mid-ocean ridges and the subsequent development of the theory of plate tectonics in the mid-20th century provided strong support for Wegener's idea, showing that tectonic plates indeed move and carry continents with them.
