Q

In 1915, German Geologist Alfred Wagner proposed that the Earth’s crust is not solid but made up of plates moving up the mantle. He examined the shape of the continents, rock structures, and recovered fossils to come up with his theory. He believed there was once a supercontinent called Pangea and a sea called Panthalassa
