Name primary source in the ocean?
Answers
Answer:
Primary sources are documents, images or artifacts that provide firsthand testimony or direct evidence concerning an historical topic under research investigation.
Answer:
Textbooks and teachers often tell students about German scientist Alfred Wegener who went public in 1912 with his theory of continental drift. The scientific community during Wegener’s lifetime did not widely accept the proposition that continents had shifted and often derided colleagues who entertained the theory. Even as Marie Tharp was creating maps in the 1950s, scientists were actively constructing ideas and compiling evidence related to seafloor spreading and magnetic striping.

One piece of evidence that influenced Wegener’s ideas about connected continents came from similarities among fossilized flora and fauna as well as geologic formations found on continents separated by oceans. While Wegener argued that continents were part of one large supercontinent, other scientists argued that land bridges facilitated the transportation of living things from continent to continent. These land bridges would have been in addition to the land bridge across the Bering Strait.
