Question

Quizplus · Accepted Answer

The military needs during World War II led to a significant boost in seafloor exploration and bathymetric understanding. The development of sonar technology during the war allowed for more detailed mapping of the seafloor, and the discovery of seafloor features such as mid-ocean ridges and trenches. This increased understanding of the seafloor also led to the theory of plate tectonics in the 1960s.
