Detailed explanation-1: -Which key component should be included in a presentation on Alfred Wegener’s hypothesis of continental drift? There are two types of plates, continental and oceanic. The continents’ movement causes land features. Convection currents in Earth’s mantle move the plates.
Detailed explanation-2: -The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
Detailed explanation-3: -The Atlantic coasts of Africa and South America appear to fit together neatly, like the pieces of a jigsaw puzzle. The same shape is also traced out by the Mid-Atlantic Ridge, shown on this map by the light-colored area (representing relatively shallow seas) between the two continents.
Detailed explanation-4: -The theory of continental drift simply stated that continents drifted from one location to another over time. Wegener noticed that the coasts of South America and Africa seemed to fit together like a puzzle. Upon further investigation he noticed the following clues that he used to support his hypothesis.
