Question

Which discovery made through ocean-floor mapping led to information that advanced the theory of continental drift? Question 5 options: The ocean floor was flat and had no geological features similar to those on land. The ocean floor has no geologic processes linked or similar to those on land. Ocean sediment was thinner than it should have been if the ocean floor had always been in the same place. Ocean sediment was thicker than it should have been for the ocean floor to be linked to processes on land.

Answer 1

Seafloor mapping during WWI and the Cold War had revealed the details of the physical structure of the ocean ridge system, and discovery of magnetic stripes on the ocean floor was the crucial turning point in development of plate tectonic theory. when deep-sea line soundings (bathymetric surveys) were routinely made in the Atlantic and Caribbean.
